<10> By performing the procedures above, an arbitrary carrier clock is obtained. To stop the count operation, clear
TMHE1 to 0.
If the setting value of the CMP01 register is N, the setting value of the CMP11 register is M, and the count clock
frequency is f
• Carrier clock output cycle = (N + M + 2)/f
• Duty = High-level width/carrier clock output width = (M + 1)/(N + M + 2)
Cautions 1. Be sure to set the CMP11 register when starting the timer count operation (TMHE1 = 1)
Remarks 1. For the setting of the output pin, refer to 8.3 (4) Port mode register 0 (PM0), port mode register
2. For how to enable the INTTMH1 signal interrupt, refer to CHAPTER 17
2. Set so that the count clock frequency of TMH1 becomes more than 6 times the count clock
3. Set the values of the CMP01 and CMP11 registers in a range of 01H to FFH.
4. The set value of the CMP11 register can be changed while the timer counter is operating.
5. Be sure to set the RMC1 bit before the count operation is started.

FUNCTIONS.
after the timer count operation was stopped (TMHE1 = 0) (be sure to set again even if
setting the same value to the CMP11 register).
frequency of TM51.
However, it takes the duration of three operating clocks (signal selected by the CKS12 to
CKS10 bits of the TMHMD1 register) since the value of the CMP11 register has been
changed until the value is transferred to the register.
, the carrier clock output cycle and duty are as follows.
