TIMERS
The ADuC7122 has five general-purpose timers/counters.
Timer0
Timer1
Timer2 or wake-up timer
Timer3 or watchdog timer
Timer4
The five timers in their normal mode of operation can be either
free-running or periodic.
In free-running mode, the counter decrements/increments
from the maximum/minimum value until zero scale/full scale
and starts again at the maximum/minimum value.
In periodic mode, the counter decrements/increments from the
value in the load register (TxLD MMR) until zero scale/full
scale and starts again at the value stored in the load register.
The value of a counter can be read at any time by accessing its
value register (TxVAL). Timers are started by writing in the
control register of the corresponding timer (TxCON).
In normal mode, an IRQ is generated each time the value of the
counter reaches zero if counting down, or full scale if counting
up. An IRQ can be cleared by writing any value to the clear
register of the particular timer (TxCLRI).
The event selection feature allows flexible interrupt generation
based on Timer0 and Timer1. T0CON and T1CON can be used
to configure the interrupt sources, as shown in Table 142. When
either Timer0 or Timer1 expires, an interrupt occurs based on
the event selection in T0CON and T1CON MMRs.

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 is
clocked from the core clock, with a prescaler of 1, 16, 256, or
32,768. This gives a minimum resolution of 22 ns when the core
is operating at 41.78 MHz and with a prescaler of 1. Timer0 can
also be clocked from the undivided core clock, internal 32 kHz
oscillator, or external 32 kHz crystal.
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 that is loaded into the counter. The
current counter value can be read from T0VAL0. Timer0 has a
capture register (T0CAP) that can be triggered by a selected IRQ’s
source initial assertion. When 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.
Timer0 reloads the value from T0LD either when TIMER0
overflows or immediately when T0CLRI is written.
