Counter/Timers.
There are two 8-bit programmable
counter/timers (T0-T1), each driven by its own 6-bit pro-
grammable prescaler. The T1 prescaler is driven by inter-
nal or external clock sources; however, the T0 prescaler is
driven by the internal clock only (Figure 19).
The 6-bit prescalers can divide the input frequency of the
clock source by any integer number from 1 to 64. Each
prescaler drives its counter, which decrements the value
(1 to 256) that has been loaded into the counter. When the
counter reaches the end of the count, a timer interrupt re-
quest, IRQ4 (T0) or IRQ5 (T1), is generated.
The counters can be programmed to start, stop, restart to
continue, or restart from the initial value. The counters can
also be programmed to stop upon reaching zero (single
pass mode) or to automatically reload the initial value and
continue counting (modulo-n continuous mode).
The counters,
but not the prescalers
, are read at any
time without disturbing their value or count mode. The
clock source for T1 is user-definable and is either the inter-
nal microprocessor clock divide-by-four, or an external sig-
nal input through Port 3. The Timer Mode register config-
ures the external timer input (P31) as an external clock, a
trigger input that can be retriggerable or non-retriggerable,
or as a gate input for the internal clock. The counter/timers
can be cascaded by connecting the T0 output to the input
of T1. T
IN
Mode is enabled by setting R243 PRE1 Bit D1
to 0.
