In order to use this module, other parts of the system must be configured correctly, as described
below.
If the CPU enters a sleep mode that disables the PDCA clocks, the PDCA will stop functioning
and resume operation after the system wakes up from sleep mode.
The PDCA has two bus clocks connected: One High Speed Bus clock (CLK_PDCA_HSB) and
one Peripheral Bus clock (CLK_PDCA_PB). These clocks are generated by the Power Man-
ager. Both clocks are enabled at reset, and can be disabled by writing to the Power Manager. It
is recommended to disable the PDCA before disabling the clocks, to avoid freezing the PDCA in
an undefined state.
The PDCA interrupt request lines are connected to the interrupt controller. Using the PDCA
interrupts requires the interrupt controller to be programmed first.
