When 8-bit timer counter H1 and compare register 01 (CMP01) match, an interrupt request signal (INTTMH1) is
Compare register 11 (CMP11) is not used in interval timer mode. Since a match of 8-bit timer counter H1 and the
By setting bit 0 (TOEN1) of timer H mode register 1 (TMHMD1) to 1, a square wave of any frequency (duty = 50%)
When using the P20/TOH1 pin for timer output, clear PM20, the output latch of P20 to 0.
PM2 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets PM2 to FFH.
