Sleep Operation
In master mode all module clocks are halted, and the transmission/reception will remain in that
state until the device wakes from sleep. After the device returns to normal mode, the module will
continue to transmit/receive data.
In slave mode, the SPI transmit/receive shift register operates asynchronously to the device. This
allows the device to be placed in sleep mode, and data to be shifted into the SPI transmit/receive
shift register. When all 8-bits have been received, the SSP interrupt flag bit will be set and if
enabled will wake the device from sleep.
