Pin Functions

As shown in Table 9-31, the port H pin functions can be switched, bit by bit, by changing the
values of OE1A to OE1H of motor control PWM timer PWOCR1 and PHDDR.

Port J

9.15.1

Overview

Port J is an 8-bit I/O port. Port J pins also function as motor control PWM timer output pins
(PWM2A to PWM2H).
Figure 9-14 shows the port J pin configuration.
