Table 67. SPI Diagnostic State Register (SPIDST)
SPI Diagnostic State Register
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).
1 = SS pin driven High (1).
This bit has no effect if SSIO = 0 or SPI configured as a Slave.
The SPI Diagnostic State register
is a read only register used for SPI diagnostics.
SCKEN—Shift Clock Enable
0 = The internal Shift Clock Enable signal is deasserted
1 = The internal Shift Clock Enable signal is asserted (shift register is updates on next
TCKEN—Transmit Clock Enable
0 = The internal Transmit Clock Enable signal is deasserted.
1 = The internal Transmit Clock Enable signal is asserted. When this is asserted the
