Note For 30- to 128-pin products, channel 2 and 3 can be set P15 and P14 with setting the bit 0 of the peripheral I/O
redirection register (PIOR) to “1”.
Remarks 1. When timer input and timer output are shared by the same pin, either only timer input or only timer output
can be used.
2. −: There is no timer I/O pin, but the channel is available. (However, the channel can only be used as an
interval timer.)
×: The channel is not available.
3. “(P1x)” indicates an alternate port when the bit 0 of the peripheral I/O redirection register (PIOR) is set to “1”.
Figures 6-1 and 6-2 show the block diagrams of the timer array unit.
