Timer 1, Timer 2, Timer 3
Timer 1, timer 2, and timer 3 are 8-bit timers. The count source for
each timer can be selected by timer 123 mode register. The timer
latch value is not affected by a change of the count source. How-
ever, because changing the count source may cause an
inadvertent count down of the timer.
Therefore, rewrite the value of timer whenever the count source is
changed.
Timer 2 Write Control
If the timer 2 write control bit is “0”, when the value is written in the
address of timer 2, the value is loaded in the timer 2 and the latch
at the same time.
If the timer 2 write control bit is “1”, when the value is written in the
address of timer 2, the value is loaded only in the latch. The value
in the latch is loaded in timer 2 after timer 2 underflows.
Note on Timer 1 to Timer 3
When the count source of timer 1 to 3 is changed, the timer count-
ing value may be changed large because a thin pulse is generated
in count input of timer. If the count source of timer 2 or timer 3 is
connected to timer 1 output, when timer 1 is written, the counting
value of timer 2 or timer 3 may be changed large because a thin
pulse is generated in timer 1 output.
Therefore, set the value of timer in the order of timer 1 , timer 2
and timer 3 after the count source selection of timer 1 to 3.
