9.13.4
The correspondence between the register specification and the pin functions is shown below.
9.14
Port J is an 8-bit I/O port. Port J pins also function as motor control PWM timer output pins.
• Port J data direction register (PJDDR)
• Port J data register (PJDR)
• Port J register (PORTJ)
9.14.1
PJDDR is a write-only register, the individual bits of which specify input or output for the pins of
port J. PJDDR cannot be read; if it is, an undefined value will be read.

Setting a PJDDR bit to 1 makes the corresponding port
J pin an output pin, while clearing the bit to 0 makes the
pin an input pin.
