Cautions 4. With the 78K0/IY2, the actual output of the <TOH1>/P34/TOX11/<TI51>/INTP4 pin is determined by
PM34 and P34, in addition to the TOH1 output.
5. With the 78K0/IA2 or 78K0/IB2 (32 pins), the actual output of the <TOH1>/P00/TI000/<TI51>/INTP0
pin or <TOH1>/P34/TOX11/<TI51>/INTP4 pin is determined by PM00 and P00 or PM34 and P34, in
addition to the TOH1 output.
6. With the 78K0/IB2 (30 pins), the actual output of the TOH1/P30/TI51/INTP1 pin is determined by
PM30 and P30, in addition to the TOH1 output.

IL: Internal low-speed oscillation clock frequency
(2) 8-bit timer H carrier control register 1 (TMCYC1)
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 signal generation clears this register to 00H.

Caution Do not rewrite RMC1 when TMHE = 1. However, TMCYC1 can be refreshed (the same value is
written).
