PIC18(L)F2X/4XK22

Idle mode allows users to substantially reduce power
consumption by stopping the CPU clock. Even so,
peripheral modules still remain clocked, and thus, con-
sume power. There may be cases where the applica-
tion needs what IDLE mode does not provide: the
allocation of power resources to the CPU processing
with minimal power consumption from the peripherals.
PIC18(L)F2X/4XK22 family devices address this
requirement by allowing peripheral modules to be
selectively disabled, reducing or eliminating their
power consumption. This can be done with control bits
in the Peripheral Module Disable (PMD) registers.
These bits generically named XXXMD are located in
control registers PMD0, PMD1 or PMD2.

Setting the PMD bit for a module disables all clock
sources
consumption to an absolute minimum. In this state, the
control and STATUS registers associated with the
peripheral are also disabled, so writes to these
registers have no effect and read values are invalid.
