TIMER0—GENERAL-PURPOSE TIMER
Timer0 is a general-purpose 16-bit count-up/count-down timer.
Timer0 is clocked from the core clock with a prescalar of either
1 or 16,384. This gives a minimum resolution of 1.6 ms with a
prescalar of 16,384, and the timer can count for more than
1 minute.
Timer0 can count up or count down. A 16-bit value can be
written to T0LD that is loaded into the counter. The current
counter value can be read from T0VAL. Timer0 reloads the
value from T0LD either when Timer0 overflows.
The Timer0 interface consists of four MMRs.

Access:
Function:
T0LD is a 16-bit register that holds the 16-bit value that is
loaded into the counter.
T0VAL is a 16-bit register that holds the 16-bit current
value of Timer0.
T0CLRI is an 8-bit register. Writing any value to this
register clears the Timer0 interrupt.
T0CON is a 16-bit configuration register described in
Table 46.

Read only
T0VAL is a 16-bit register that holds the
current value of Timer0.
T0CON
0xFFFF0308
0x0000
Read/write
This 16-bit MMR configures the mode of
operation for Timer0.
