DIAG—Diagnostic Mode Control bit
This bit is for SPI diagnostics. Setting this bit allows the Baud Rate Generator value to be
read using the SPIBRH and SPIBRL register locations.
0 = Reading SPIBRH, SPIBRL returns the value in the SPIBRH and SPIBRL registers
1 = Reading SPIBRH returns bits [15:8] of the SPI Baud Rate Generator; and reading
