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 provides observability of internal state. This 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
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 serial
data out is updated on the next system clock (MOSI or MISO).
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. When configured as a general purpose
timer, the interrupt interval is calculated using the following equation:
Interrupt Interval (s) = System Clock Period (s) × BRG[15:0]
