TD1/0
These are the timer source clock frequency selection bits (see Table 9). These bits
determine the source clock for the countdown timer (see Table 10). When not in use, the
TD1 and TD0 bits should be set to ‘11’ (1/60 Hz) for power saving.
Note:
Writing to the timer register will not reset the TF bit or clear the interrupt.
