The SPI controller is in Word mode if the data character is greater than 8 bits in length.
The CPM performance factor assumes a 32-bit peripheral port size. The CPM
performance for 16- and 8-bit port sizes would be one-quarter and one-half of those
listed.
The CPM performance factor is independent of port size. The CPM performance factor
is identical for 8-, 16-, and 32-bit port sizes. However, if the bus cycle is slow enough
(more than 13 clocks), performance will be degraded.
