17.3.8
In Master mode, module clocks may be operating at a
different speed than when in full-power mode, or in the
case of the power-managed Sleep mode, all clocks are
halted.
In most power-managed modes, a clock is provided
to the peripherals and is derived from the primary
clock source, the secondary clock (Timer1 oscillator
at 32.768 kHz) or the internal oscillator block (one of
eight frequencies between 31 kHz and 8 MHz). See
Section 2.7
Switching” for additional information.
In most cases, the speed that the master clocks SPI
data is not important; however, this should be
evaluated for each system.
If MSSP interrupts are enabled, they can wake the con-
troller from a power-managed mode when the master
completes sending data. If an exit from a power-
managed 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 pause until
the device wakes from the power-managed mode.
After the device returns to full-power mode, the module
will resume transmitting and receiving data.

17.3.8.1
In 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 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 MSSP interrupts are
enabled, will wake the device from a power-managed
mode.
17.3.9
A Reset disables the MSSP module and terminates the
current transfer.

Table 17-1 shows the compatibility between the
standard SPI modes and the states of the CKP and
CKE control bits.
