counter Hn and the CMP0n register match after the timer count is started. PWM output (TOHn output) outputs an
inactive level when 8-bit timer counter Hn and the CMP1n register match.
TMHMDn
In PWM output mode, a pulse with an arbitrary duty and arbitrary cycle can be output.
The 8-bit timer compare register 0n (CMP0n) controls the cycle of timer output (TOHn). Rewriting the CMP0n
The 8-bit timer compare register 1n (CMP1n) controls the duty of timer output (TOHn). Rewriting the CMP1n
The operation in PWM output mode is as follows.
PWM output (TOHn output) outputs an active level and 8-bit timer counter Hn is cleared to 0 when 8-bit timer

Setting
(i) Setting timer H mode register n (TMHMDn)
(ii) Setting CMP0n register
(iii) Setting CMP1n register
When the values of the 8-bit timer counter Hn and the CMP0n register match, the 8-bit timer counter Hn is
cleared, an interrupt request signal (INTTMHn) is generated, and an active level is output. At the same time,
the compare register to be compared with the 8-bit timer counter Hn is changed from the CMP0n register to
the CMP1n register.
register to be compared with the 8-bit timer counter Hn is changed from the CMP1n register to the CMP0n
register. At this time, the 8-bit timer counter Hn is not cleared and the INTTMHn signal is not generated.
