Bus Clock
Run mode
This is the basic mode of operation.
Wait mode
PIT operation in wait mode is controlled by the PITSWAI bit located in the PITCFLMT register.
In wait mode, if the bus clock is globally enabled and if the PITSWAI bit is clear, the PIT operates
like in run mode. In wait mode, if the PITSWAI bit is set, the PIT module is stalled.
Stop mode
In full stop mode or pseudo stop mode, the PIT module is stalled.
Freeze mode
PIT operation in freeze mode is controlled by the PITFRZ bit located in the PITCFLMT register.
In freeze mode, if the PITFRZ bit is clear, the PIT operates like in run mode. In freeze mode, if the
PITFRZ bit is set, the PIT module is stalled.
