24.2.6
In SPI Master mode, module clocks may be operating
at a different speed than when in Full-Power mode; in
the case of the Sleep mode, all clocks are halted.
Special care must be taken by the user when the
MSSPx clock is much faster than the system clock.
In Slave mode, when MSSPx interrupts are enabled,
after the master completes sending data, an MSSPx
interrupt will wake the controller from Sleep.
If an exit from Sleep mode is not desired, MSSPx inter-
rupts should be disabled.

In SPI Master mode, when the Sleep mode is selected,
all module clocks are halted and the transmis-
sion/reception will remain in that state until the device
wakes. After the device returns to Run mode, the mod-
ule will resume transmitting and receiving data.
In SPI 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
MSSPx interrupt flag bit will be set and if enabled, will
wake the device.
