RESET:
RESET:
Always read zero
In normal modes, PR1 and PR0 can only be written once, and the write must occur within 64 cycles
after reset. Refer to Table 10 for specific timing values.
Clear flags by writing a one to the corresponding bit position(s).
Set when TCNT changes from $FFFF to $0000
Refer to 11 Pulse Accumulator.
Refer to 11 Pulse Accumulator.
Always read zero
