4559 Group
The 4559 Group timer consists of the following circuits.
Prescaler : 8-bit programmable timer
Timer 1 : 8-bit programmable timer
Timer 2 : 8-bit programmable timer
Timer 3 : 16-bit fixed frequency timer
Timer LC : 4-bit programmable timer
Watchdog timer: 16-bit fixed frequency timer
(Timers 1, 2 and 3 have the interrupt function, respectively)
Prescaler, timer 1, timer 2, timer 3 and timer LC can be
controlled with the timer control registers PA and W1 to W4. The
watchdog timer is a free counter which is not controlled with the
control register.
Each function is described below.
