• Manufacturer Part Number: upd78f0730
• Description: 8-bit Single-chip Microcontroller
• Manufacturer: Renesas Electronics Corporation.

Cautions 1. When TMHE1 = 1, setting the other bits of TMHMD1 is prohibited.
Remarks 1. f

2. In the PWM output mode and carrier generator mode, be sure to set 8-bit timer H compare
3. When the carrier generator mode is used, set so that the count clock frequency of TMH1

operation was stopped (TMHE1 = 0) (be sure to set again even if setting the same value to
CMP11).
