6. 16-bit Reload Timer (with Event Count Function)
The 16-bit reload timer consists of a 16-bit down counter, a 16-bit reload register, control register, and 4 timer
pins (I/O set by timer pin select register). Three internal clocks and an external clock can be selected as input
clocks. A toggle output waveform is output at the output pin (TOT) in reload mode, while a square wave indicating
that the timer is counting is output at the output pin in single-shot mode. The input pin (TIN) can be used for
event input in even count mode, and for trigger input or gate input in internal clock mode.
This product has this timer built into four channels.
