Notes 1. When selecting f
IL as the count source, set the WUTMMCK0 bit in the operation speed mode control register
(OSMC) to 1.
2. The polarity can be selected by the RCCPSEL2 bit in the TRJISR0 register.
3. f
SUB cannot be selected as the count source for timer RJ when fSL (fIL) is selected as the count source for timer
RD or the output clock for clock output/buzzer output.
4. The 20-pin products do not have TRJIO0 and TRJO0 pins.
7.2 I/O Pins
Table 7-2 lists the Timer RJ Pin Configuration.
