FIFO Mode Enable
Enables or disables the FIFO mode. When FIFO mode
is enabled two 8-entry deep FIFOs are made available,
one for transmit data and one for receive data. These
FIFOs are read and written via SPTBR and SPRBR.
When FIFO mode is disabled the SPTBR and SPRBR
are used directly so new data must be written to SPTBR
and read from SPRBR for each and every transfer.
FIFO mode must be disabled if DMA requests are also
going to be used to service SPTBR and SPRBR.
0: FIFO mode disabled
1: FIFO mode enabled

Chip Select Value
Controls the value output from the chip select when the
HSPI is a master and the chip select generation has
been selected.
0: Chip select output is low.
1: Chip select output is high.

R/W
Automatic/Manual Chip Select
0: Chip select output is automatically generated during
data transfer.
1: Chip select output is manually controlled, with its
value being determined by the CSV bit.
