■ Counter Operating Mode
● Reload mode
When an underflow occurs in the 16-bit downcounter ("0x0000"
the 16-bit reload timer reload register ch. n (TMRLRHn/TMRLRLn) is loaded to the 16-bit
downcounter and the 16-bit reload timer continues counting. In addition, since the interrupt
request is output by an underflow, the 16-bit reload timer can be used as the interval timer.
● One-shot mode
An interrupt is generated when an underflow occurs on the 16-bit downcounter.
During counter operation, the TOn pin outputs a square waveform indicating that the counter is
currently running.
