9.1.7
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 eight bits have been received, the SSPIF
interrupt flag bit will be set and if enabled will wake the
device from SLEEP.
TABLE 9-1:
Legend: x = unknown, u = unchanged, - = unimplemented read as ’0’. Shaded cells are not used by the MSSP in SPI mode.
