FAQ
What is the limitation of SPI 2-bit transfer mode? Issue Date：2015-07-09
For NuMico® M051BN, NUC122, NUC130 and NUC140 series, SPI supports single and burst transfer mode. However, in 2-bit transfer mode, it only supports the single mode (TX_NUM(SPI_CNTRL[9:8])=0x00). In 2-bit transfer mode, the registers SPI_Tx0 and SPI_Rx0 are mapping to the channel 0 (MISOx0, MOSIx0), but the registers SPI_Tx1 and SPI_Rx1 are mapping to the channel 1 (MISOx1, MOSIx1).
