Caution:
SPI Mode Register
7
The SPI Mode Register configures the character bit width and the direction and value of
the SS pin.
Reserved—Must be 0
DIAG–Diagnostic Mode Control bit
This bit is for SPI diagnostics. Setting this bit allows the BRG 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
SPIBRL returns bits [7:0] of the SPI Baud Rate Counter. The Baud Rate Counter High and
Low byte values are not buffered.
NUMBITS[2:0]—Number of Data Bits Per Character to Transfer
This field contains the number of bits to shift for each character transfer. See the SPI Data
Register description for information on valid bit positions when the character length is less
than 8-bits.
000 = 8 bits
001 = 1 bit
010 = 2 bits
011 = 3 bits
100 = 4 bits
101 = 5 bits
110 = 6 bits
111 = 7 bits
SSIO—Slave Select I/O
0 = SS pin configured as an input.
1 = SS pin configured as an output (MASTER mode only).
SSV—Slave Select Value
If SSIO = 1 and SPI configured as a Master:
0 = SS pin driven Low (0).
Reserved
Take precautions if you are reading the values while BRG is counting.
