NuMicro™ NUC100 Series Technical Reference Manual
Two Bit Transfer Mode
This SPI controller also supports two-bit transfer mode when enabling the TWOB bit
(SPI_CNTRL[22]). When the TWOB bit is enabled, it can transmit and receives two-bit serial data
st
simultaneously. The 1
bit through the MOSIx0 and MISOx0 pins to transmit the data from the
nd
SPI_TX0 register and receive the data into the SPI_RX0 register. The 2
bit through the MOSIx1
and MISOx1 pins to transmit the data from the SPI_TX1 register and receive the data into the
SPI_RX1 register. Note that when enable the TWOB bit, the setting of TX_NUM must be
programmed as 0x00 only.
