ADuC7033
TIMERS
The ADuC7033 features five general-purpose timer/counters.

The five timers in their normal mode of operation can either be
free running or periodic.
In free running mode, the counter decrements/increments from
the maximum/minimum value until zero/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/full scale and
starts again at the value stored in the load register. Note that the
TxLD MMR should be configured before the TxCON MMR.
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

Timer2 or wake-up timer

Timer4 or STI timer

counting up). An IRQ can be cleared by writing any value to the
clear register of the particular timer (TxCLRI).
