Series Technical Reference Manual
1 = If this bit is set, SPISS0/1 signal is generated automatically. It means that
device/slave select signal, which is set in SSR[0] register is asserted by the SPI
controller when transmit/receive is started by setting GO_BUSY, and is de-
asserted after each transmit/receive is finished.
Slave Select Active Level
It defines the active level of slave select signal (SPISS0/1).
0 = The slave select signal SPISS0/1 is active at low-level/falling-edge.
1 = The slave select signal SPISS0/1 is active at high-level/rising-edge.
Reserved
Slave Select Register (Master only)
If AUTOSS bit is cleared, writing 1 to this bit sets the SPISSx line to an active
state and writing 0 sets the line back to inactive state.
If AUTOSS bit is set, writing 1 to this bit will select the SPISSx line to be
automatically driven to active state for the duration of the transmit/receive, and
will be driven to inactive state for the rest of the time. (The active level of
SPISSx is specified in SS_LVL).
Note: SPISSx is always defined as device/slave select input signal in slave
mode.
