TIMER1 OR WAKE-UP TIMER
Timer1 is a 32-bit wake-up timer, count down or count up, with
a programmable prescaler. The prescaler is clocked directly from
one of four clock sources, namely, the core clock (which is the
default selection), the low power 32.768 kHz oscillators, external
32.768 kHz watch crystal, or the precision 32.768 kHz oscillator.
The selected clock source can be scaled by a factor of 1, 16, 256,
or 32,768. The wake-up timer continues to run when the core
clock is disabled. This gives a minimum resolution of 97.66 ns
when operating at CD zero, the core is operating at 10.24 MHz,
and with a prescaler of 1 (ignoring the external GPIOs).
The counter can be formatted as a plain 32-bit value or as
hours:minutes:seconds:hundredths.
Timer1 reloads the value from T1LD either when Timer1
overflows or immediately when T1CLRI is written.
The Timer1 interface consists of four MMRS.

•
•
T1LD and T1VAL are 32-bit registers and hold 32-bit,
unsigned integers. T1VAL is read only.
T1CLRI is an 8-bit register. Writing any value to this
register clears the Timer1 interrupt.
T1CON is the configuration MMR, described in Table 80.

Read and write
T1LD is a 32-bit register that holds the 32-bit
value that is loaded into the counter.
T1CLRI
0xFFFF034C
Write only
This 8-bit, write-only MMR is written (with
any value) by user code to clear the interrupt.
T1VAL
0xFFFF0344
0xFFFFFFFF
Read only
T1VAL is a 32-bit register that holds the
current value of Timer1.
