SPI Baud Rate (bits/s)
The SPI Baud Rate High and Low Byte registers combine to form a 16-bit reload value,
BRG[15:0], for the SPI Baud Rate Generator. The reload value must be greater than or
equal to
divided by 4). The SPI baud rate 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.
