Example: To output a 2 [ms] one-shot pulse with a 3 [ms] delay to the external trigger pulse via the TB1IN0 pin.
* Clock state : Clock gear 1/1 (fc)
Setting in Main
Set free running.
Count using
φT1.
TB1MOD
← X X 1 0 1 0 0 1
Load into TB1CP0H/L by rising edge of TB1IN0 pin input.
TB1FFCR
← X X 0 0 0 0 1 0
Clear TB1FF0 to 0.
Disable inversion of TB1FF0.
PDCR ← X X X X − 1 − −
PDFC ← X X X X − 1 X X
Set PD2 to function as the TB1OUT0 pin.
INTE45
← X − − − X 1 0 0
INTETB1 ← X 0 0 0 X 0 0 0
Enable INT4. Disable INTTB10 and INTTB11.
TB1RUN ← − 0 X X − 1 X 1 Start TMRB0.
Setting in INT4
TB1RG0H/L
← TB1CP0H/L + 3 ms/φT1
TB1RG1H/L
← TB1RG0H/L + 2 ms/φT1
TB1FFCR
← X X − − 1 1 − −
Enable inversion of TB1FF0 when match with
TB1RG0G/L or TB1RG1G/L.
INTETB1
← X 1 0 0 X − − −
Set INTTB11 to enable.
Setting in INTTB11
TB1FFCR
← X X − − 0 0 − −
Disable inversion of TB1FF0 when match with
TB1RG0H/L or TB1RG1H/L.
INTETB1
← X 0 0 0 X − − − Disable
INTTB11.
X : Don’t care,
− : No change
When delay time is unnecessary, invert timer flip-flop TB1FF0 when up counter
value is loaded into capture register (TB1CP0H/L), and set the TB1CP0H/L value (c)
plus the one-shot pulse width (p) to TB0RG1H/L when the interrupt INT4 occurs. The
TB1FF0 inversion should be enable when the up counter (UC12) value matches
TB1RG1H/L, and disabled when generating the interrupt INTTB11.
