Cautions 1. When TMHE1 = 1, setting the other bits of TMHMD1 is prohibited. However, TMHMD1 can be
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 signal generation clears this register to 00H.
Caution Do not rewrite RMC1 when TMHE = 1. However, TMCYC1 can be refreshed (the same value is
