(2) 8-bit timer H carrier control register 1 (TMCYC1)
(3) Port mode register 1 (PM1)
200
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 sets this register to 00H.
This register sets port 1 input/output in 1-bit units.
When using the P16/TOH1 pin for timer output, clear PM16 and the output latches of P16 to 0.
PM1 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.
