TIMER0—LIFETIME TIMER
Timer0 is a general-purpose, 48-bit count up, or a 16-bit count
up/down timer with a programmable prescaler. Timer0 can be
clocked from either the core clock or the low power 32.768 kHz
oscillator with a prescaler of 1, 16, 256, or 32,768. This gives a
minimum resolution of 48.83 ns when the core is operating at
20.48 MHz with a prescaler of 1.
In 48-bit mode, Timer0 counts up from zero. The current
counter value can be read from T0VAL0 and T0VAL1.
In 16-bit mode, Timer0 can count up or count down. A 16-bit
value can be written to T0LD to load into the counter. The cur-
rent counter value is read from T0VAL0. Timer0 has a capture
register (T0CAP) triggered by a selected IRQ source initial
assertion. When triggered, the current timer value is copied to
T0CAP and the timer continues running. This feature can be
used to determine the assertion of an event with more accuracy
than by servicing an interrupt alone.
Timer0 reloads the value from T0LD when Timer0 overflows.
The Timer0 interface consists of six MMRS.

T0LD is a 16-bit register holding the 16-bit value that
is loaded into the counter. T0LD is only available in
16-bit mode.
T0CAP is a 16-bit register that holds the 16-bit value
captured by an enabled IRQ event. T0CAP is only
available in 16-bit mode.
T0VAL0/T0VAL1 are 16-bit and 32-bit registers that hold
the 16 least significant bits (LSBs) and 32 most significant
bits (MSBs), respectively. T0VAL0 and T0VAL1 are read
only. In 16-bit mode, 16-bit T0VAL0 is used. In 48-bit
mode, both 16-bit T0VAL0 and 32-bit T0VAL1 are used.

CAPTURE
T0CLRI is an 8-bit register. Writing any value to this
register clears the interrupt. T0CLRI is only available in
16-bit mode.
T0CON is the configuration MMR described in Table 53.

T0VAL0 and T0VAL1 are 16-bit and 32-bit
registers that hold the 16 LSBs and 32 MSBs,
respectively. T0VAL0 and T0VAL1 are read
only. In 16-bit mode, 16-bit T0VAL0 is used.
In 48-bit mode, both 16-bit T0VAL0 and
32-bit T0VAL1 are used.
