4571 Group
TIMERS
The 4571 Group has the following timers.
Programmable timer
The programmable timer has a reload register and enables the
frequency dividing ratio to be set. It is decremented from a
setting value n. When it underflows (count to n + 1), a timer
interrupt request flag is set to “1,” new data is loaded from the
reload register, and count continues (auto-reload function).
Fixed dividing frequency timer
The fixed dividing frequency timer has the fixed frequency
dividing ratio (n). An interrupt request flag is set to “1” after
every n count of a count pulse.
