SPI Clock Rate.
These bits determine the frequency of the SCK output when the SPI module is
configured for master mode operation. The SCK clock frequency is a divided
version of the system clock, and is given in the following equation, where SYSCLK
is the system clock frequency and SPI1CKR is the 8-bit value held in the SPI1CKR
register.
for 0 <= SPI0CKR <= 255
Example: If SYSCLK = 2 MHz and SPI1CKR = 0x04,
