SPI Baud Rate High and Low Byte Registers

7
The SPI Baud Rate High and Low Byte registers
a 16-bit reload value, BRG[15:0], for the SPI Baud Rate Generator.
When configured as a general purpose timer, the SPI BRG interrupt interval is calculated
using the following equation:
BRH = SPI Baud Rate High Byte
Most significant byte, BRG[15:8], of the SPI Baud Rate Generator’s reload value.
BRL = SPI Baud Rate Low Byte
Least significant byte, BRG[7:0], of the SPI Baud Rate Generator’s reload value.
