19.2.8 Operation in Sleep Modes
The SPI module can operate in all sleep modes by setting the run_in_standby option in the spi_config struct. The operation in slave and master mode is shown in the table below.
run_in_standby | Slave | Master |
|---|---|---|
false | Disabled, all reception is dropped | GCLK is disabled when master is idle, wake on transmit complete |
true | Wake on reception | GCLK is enabled while in sleep modes, wake on all interrupts |
