NOTE:
PDBG — Debug Mode Bit
The read/write PDBG bit controls the function of the PIT in debug
mode. Reset clears PDBG.
1 = PIT function stopped in debug mode
0 = PIT function not affected in debug mode
During debug mode, register read and write accesses function
normally. When debug mode is exited, timer operation continues from
the state it was in before entering debug mode, but any updates made
in debug mode remain.
Changing the PDBG bit from 1 to 0 during debug mode starts the PIT
timer. Likewise, changing the PDBG bit from 0 to 1 during debug mode
stops the PIT timer.
