| Bits | Field | Descriptions |
|---|---|---|
| [0] | PDMACEN | PDMA Channel Enable |
| Setting this bit to "1" enables PDMA's operation. | ||
| If this bit is cleared, PDMA will ignore all PDMA request and force Bus Master into IDLE state. | ||
| Note: SW_RST will clear this bit. | ||
| [1] | SW_RST | Software Engine Reset |
| 0 = No effect. | ||
| 1 = Reset the internal state machine and pointers. | ||
| The contents of control register will not be cleared. | ||
| This bit will auto clear after few clock cycles. | ||
| [3:2] | MODE_SEL | PDMA Mode Select |
| 00 = Memory to Memory mode (Memory-to-Memory). | ||
| 01 = IP to Memory mode (APB-to-Memory). | ||
| 10 = Memory to IP mode (Memory-to-APB). | ||
| 11 = Reserved. | ||
| [5:4] | SAD_SEL | Transfer Source Address Direction Selection |
| 00 = Transfer Source address is incremented successively. | ||
| 01 = Reserved. | ||
| 10 = Transfer Source address is fixed (This feature can be used when data where transferred from a single source to multiple destinations). | ||
| 11 = Transfer Source address is wrap around (When the PDMA_CBCR equal zero, the PDMA_CSAR and PDMA_CBCR register will updated by PDMA_SAR and PDMA_BCR automatically. | ||
| PDMA will start another transfer which without software trigger until PDMA_EN disable. | ||
| When the PDMA_EN disable, the PDMA will complete the active transfer but the remained data which in the PDMA_BUF will not transfer to destination address). | ||
| [7:6] | DAD_SEL | Transfer Destination Address Direction Selection |
| 00 = Transfer Destination address is incremented successively. | ||
| 01 = Reserved. | ||
| 10 = Transfer Destination address is fixed (This feature can be used when data where transferred from multiple sources to a single destination). | ||
| 11 = Transfer Destination address is wrap around (When the PDMA_CBCR equal zero, the PDMA_CDAR and PDMA_CBCR register will updated by PDMA_DAR and PDMA_BCR automatically. | ||
| PDMA will start another transfer which without software trigger until PDMA_EN disable. | ||
| When the PDMA_EN disable, the PDMA will complete the active transfer but the remained data which in the PDMA_BUF will not transfer to destination address). | ||
| [12] | TO_EN | Time-Out Enable |
| This bit will enable PDMA internal Timer. While Timer is counted to zero, the TO_IS will be set. | ||
| 0 = PDMA internal Timer Disabled. | ||
| 1 = PDMA internal Timer Enabled. | ||
| [20:19] | APB_TWS | Peripheral Transfer Width Selection |
| 00 = One word (32 bits) is transferred for every PDMA operation. | ||
| 01 = One byte (8 bits) is transferred for every PDMA operation. | ||
| 10 = One half-word (16 bits) is transferred for every PDMA operation. | ||
| 11 = Reserved. | ||
| Note: This field is meaningful only when MODE_SEL is IP to Memory mode (APB-to-Memory) or Memory to IP mode (Memory-to-APB). | ||
| [23] | TRIG_EN | TRIG_EN |
| 0 = No effect. | ||
| 1 = PDMA data read or write transfer Enabled. | ||
| Note1: When PDMA transfer completed, this bit will be cleared automatically. | ||
| Note2: If the bus error occurs, all PDMA transfer will be stopped. | ||
| Software must reset all PDMA channel, and then trig again. |

| __IO uint32_t PDMA_T::DAR |
| Bits | Field | Descriptions |
|---|---|---|
| [31:0] | PDMA_DAR | PDMA Transfer Destination Address Register |
| This field indicates a 32-bit destination address of PDMA. | ||
| Note : The destination address must be word alignment |

| [0] | TABORT_IE | PDMA Read/Write Target Abort Interrupt Enable |
| 0 = Disabled target abort interrupt generation during PDMA transfer. | ||
| 1 = Enabled target abort interrupt generation during PDMA transfer. | ||
| [1] | TD_IE | PDMA Transfer Done Interrupt Enable |
| 0 = Disabled interrupt generator when PDMA transfer is done. | ||
| 1 = Enabled interrupt generator when PDMA transfer is done. | ||
| [5:2] | WRA_BCR_IE | Wrap Around Byte Count Interrupt Enable |
| 0001 = Interrupt enable of PDMA_CBCR equal 0. | ||
| 0100 = Interrupt enable of PDMA_CBCR equal 1/2 PDMA_BCR. | ||
| Others = Reserved. | ||
| [6] | TO_IE | Time-Out Interrupt Enable |
| 0 = Time-out interrupt Disabled. | ||

| __IO uint32_t PDMA_T::ISR |
| Bits | Field | Descriptions |
|---|---|---|
| [0] | TABORT_IS | PDMA Read/Write Target Abort Interrupt Status Flag |
| 0 = No bus ERROR response received. | ||
| 1 = Bus ERROR response received. | ||
| NOTE1: This bit is cleared by writing "1" to itself. | ||
| NOTE2: The PDMA_ISR [TABORT_IF] indicate bus master received ERROR response or not, if bus master received occur it means that target abort is happened. | ||
| PDMA controller will stop transfer and respond this event to software then go to IDLE state. | ||
| When target abort occurred, software must reset PDMA controller, and then transfer those data again. | ||
| [1] | TD_IS | Transfer Done Interrupt Status Flag |
| This bit indicates that PDMA has finished all transfer. | ||
| 0 = Not finished yet. | ||
| 1 = Done. | ||
| NOTE: This bit is cleared by writing "1" to itself. | ||
| [5:2] | WRA_BCR_IS | Wrap Around Transfer Byte Count Interrupt Status Flag |
| WAR_BCR_IS [0] (xxx1) = PDMA_CBCR equal 0 flag. | ||
| WAR_BCR_IS [2] (x1xx) = PDMA_CBCR equal 1/2 PDMA_BCR flag. | ||
| NOTE: Each bit is cleared by writing "1" to itself. | ||
| This field is only valid in wrap around mode. | ||
| (PDMA_CSR[DAD_SEL] =11 or PDMA_CSR[SAD_SEL] =11). | ||
| [6] | TO_IS | Time-Out Interrupt Status Flag |
| This flag indicated that PDMA has waited peripheral request for a period defined by PDMA_TCR. | ||
| 0 = No time-out flag. | ||
| 1 = Time-out flag. | ||
| NOTE: This bit is cleared by writing "1" to itself. |

| __IO uint32_t PDMA_T::TCR |
| Bits | Field | Descriptions |
|---|---|---|
| [15:0] | PDMA_TCR | PDMA Timer Count Setting Register |
| Each PDMA controller contains an internal counter. | ||
| The internal counter starts counting when setting PDMA_CSRx [TO_EN] register, clearing and restart counting when complete each peripheral request service. |
