15.1.7 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 MSSP inter-
rupt flag bit will be set and if enabled, will wake the
device from SLEEP.
15.1.8 EFFECTS OF A RESET
A RESET disables the MSSP module and terminates
the current transfer.
