<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, see 9.3 (3) Port mode register 1 (PM1).
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
• PWM pulse output cycle = (N + 1)/f
• Duty = (M + 1)/(N + 1)
2. For details on how to enable the INTTMHn signal interrupt, see CHAPTER 20
3. n = 0, 1
2. Be sure to set the CMP1n register when starting the timer count operation (TMHEn = 1) after the
3. Make sure that the CMP1n register setting value (M) and CMP0n register setting value (N) are
FUNCTIONS.
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.
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.
