21.3.9
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.
In Idle modes, a clock is provided to the peripherals.
That clock can be from the primary clock source, the
secondary clock (SOSC oscillator) or the INTOSC
source. See
Oscillator Switching”
In most cases, the speed that the master clocks SPI
data is not important; however, this should be
evaluated for each system.
If MSSP interrupt is enabled, it can wake the controller
from Sleep mode, or one of the Idle modes, when the
master completes sending data. If an exit from Sleep or
Idle mode is not desired, MSSP interrupts should be
disabled.
If the Sleep mode is selected, all module clocks are
halted and the transmission/reception will remain in
that state until the device wakes. After the device
returns to Run mode, the module 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 any power-managed
mode
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.
