Chip select CSI buffer register 3n (SFCS3n, SFCS3nL)
The SFCS3n register is a 16-bit buffer register that stores transmit data. It is overlayed by an 8-bit
buffer register SFCS3nL on the lower 8 bits.
When chip select data is written to the SFCS3n (SFCS3nL) register, the data is stored in the
CSIBUFn register following the CSIBUFn pointer for writing. The store operation is executed after
next write of the transmit data CSI buffer register SFDB3n (SFDB3nL).
When the data of this register is read, the value of the transmit data written last is read.
The SFCS3n register can be read or written in 16-bit units.
The SFCS3nL register can be read or written, in 8-bit or 1-bit units.
Reset input clears the SFCS3n register to FFFFH, and the SFCS3nL register to FFH accordingly.
