(1) 16-bit Free-run Timer 1, 2
The 16-bit free-run timer consists of a 16-bit up counter, a control register and a communications prescaler
register. The value output from the timer counter is used as basic time (base timer) for input capture (ICU) and
output compare (OCU).
A counter operation clock can be selected from four internal clocks (
φ/4, φ/16, φ/64 and φ/256).
An interrupt can be generated by overflow of counter value or compare match with OCU compare register 0
and 4. (Compare match requires mode settings.)
The counter value can be initialized to “0000H” by a reset, software clear or compare match with OCU compare
register 0 and 4.
