SPISTATE - SPI State Machine
Defines the current state of the internal SPI State Machine.
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 SPI baud rate is calculated using the
following equation:
Minimum baud rate is obtained by setting BRG[15:0] to
of (2 X 65536 = 131072).
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.
SPI Baud Rate (bits/s) =
