38 / 83 page  38 MB90660A Series 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.
