Preliminary Technical Data
TIMER0 – LIFE-TIME TIMER
Timer0 is a general purpose 48-bit count-up, or a 16-bit count
up/down timer with a programmable prescalar. Timer0 may be
clocked from either the Core clock, the Low Power 32.768kHz
Oscillator, the Precision 32.768kHz Oscillator or an external
32.768kHz crystal, with a prescalar of 1,16, 256 or 32768. This
gives a minimum resolution of 48.83ns when the core is
operating at 20.48MHz, and with a prescalar of 1.
In 48-bit mode, Timer0 counts up from zero. The current
counter value may be read from T0VAL0 and T0VAL1.
In 16-Bit mode,Timer0 may count up or count down. A 16-bit
value may be written to T0LD which will be loaded into the
counter. The current counter value may be read from T0VAL0.
Timer0 has a capture register (T0CAP), which may be triggered
by a selected IRQ’s source initial assertion. Once triggered, the
current timer value is copied to T0CAP, and the timer keeps
running. This feature can be used to determine the assertion of
an event with more accuracy than by servicing an interrupt
alone.

In 16-bit mode 16-bit T0VAL0 is used. In 48-bit mode both 16-
bit T0VAL0 and 32-bit T0VAL1 are used.

PRESCALER
Timer0 reloads the value from T0LD either when TIMER0
overflows, or immediately when T0CLRI is written.
Timer0 interface consists of six MMRS:
- T0LD is a 16-bit register which holds the 16 bit value that is
- T0CAP is a 16-bit register which holds the 16-bit value
- T0VAL0/T0VAL1 are 16-bit and 32-bit registers which hold
- T0CLRI is an 8-bit register. Writing any value to this register
- T0CON is the configuration MMR described in Table 44.
