<5> By performing procedures <3> and <4> repeatedly, a pulse with an arbitrary duty can be obtained.
<6> To stop the count operation, set TMHEn = 0.
Cautions 1. The set value of the CMP1n register can be changed while the timer counter is operating.
Remarks 1. For the setting of the output pin, refer to 8.3 (3) Port mode register 1 (PM1), port mode register 3
If the setting value of the CMP0n register is N, the setting value of the CMP1n register is M, and the count
clock frequency is f
2. For details on how to enable the INTTMHn signal interrupt, refer to CHAPTER 17 INTERRUPT
3. 78K0/KY2-L, 78K0/KA2-L: n = 1
2. Be sure to set the CMP1n register when starting the timer count operation (TMHEn = 1) after
3. Make sure that the CMP1n register setting value (M) and CMP0n register setting value (N) are
PWM pulse output cycle = (N + 1)/f
Duty = (M + 1)/(N + 1)

However, this takes a duration of three operating clocks (signal selected by the CKSn2 to
CKSn0 bits of the TMHMDn register) from when the value of the CMP1n register is changed
until the value is transferred to the register.
the timer count operation was stopped (TMHEn = 0) (be sure to set again even if setting the
same value to the CMP1n register).
within the following range.
