CHAPTER 8 8-BIT TIMERS H0, H1, AND H2
Cautions 1. When TMHE1 = 1, setting the other bits of TMHMD1 is prohibited. However, TMHMD1 can be
refreshed (the same value is written).
2. In the PWM output mode and carrier generator mode, be sure to set the 8-bit timer H compare
register 11 (CMP11) when starting the timer count operation (TMHE1 = 1) after the timer count
operation was stopped (TMHE1 = 0) (be sure to set again even if setting the same value to
CMP11).
3. When the carrier generator mode is used, set so that the count clock frequency of TMH1
becomes more than 6 times the count clock frequency of TM51.
4. The actual TOH1/P31/INTP3 pin output is determined depending on PM31 and P31, besides
TOH1 output.
Remarks 1. fPRS: Peripheral hardware clock frequency
2. fRL: Internal low-speed oscillation clock frequency
