Section 9 I/O Ports
After a reset and in hardware standby mode, PORTH contents are determined by the pin states, as
PHDDR and PHDR are initialized. PORTH retains its prior state in software standby mode.
9.14.3
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 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.
