Preliminary Technical Data
TIMERS
The ADuC7032 features four general purpose Timer/Counters:
The four timers in their normal mode of operation may either
be free-running or periodic.
- In free-running mode the counter decrements/increments
- In periodic mode the counter decrements/increments from
from the maximum/minimum value until zero/full scale and
starts again at the maximum /minimum value.
the value in the Load Register(TxLD MMR,) until zero/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 Clear register
of the particular timer (TxCLRI). Once TxCLRI is written to,
the Timer is reloaded with TxLD within 4 clocks of the timers
clock source.
