16.3.8
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 interrupt
flag bit will be set and if enabled, will wake the device
from SLEEP.
16.3.9
A RESET disables the MSSP module and terminates
the current transfer.

Legend: x = unknown, u = unchanged, - = unimplemented, read as '0'. Shaded cells are not used by the MSSP in SPI mode.
Note 1: The PSPIF, PSPIE and PSPIP bits are reserved on the PIC18C2X2 devices; always maintain these bits clear.
