(2) 8-bit timer H carrier control register 1 (TMCYC1)
Cautions 1. When the internal oscillation clock is selected as the clock to be supplied to the CPU, the
Remarks 1. f
Note Bit 0 is read-only.
This register controls the remote control output and carrier pulse output status of 8-bit timer H1.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears this register to 00H.

2. When TMHE1 = 1, setting the other bits of TMHMD1 is prohibited.
3. In the PWM output mode and carrier generator mode, be sure to set 8-bit timer H compare
