Port J Register (PORTJ)
PORTJ is an 8-bit read-only register that shows the pin states. It cannot be written to. Writing of
output data for the port J pins (PJ7 to PJ0) must always be performed on PJDR.
If a port J read is performed while PJDDR bits are set to 1, the PJDR values are read. If a port J
read is performed while PJDDR bits are cleared to 0, the pin states are read.
After a reset and in hardware standby mode, PORTJ contents are determined by the pin states, as
PJDDR and PJDR are initialized. PORTJ retains its prior state in software standby mode.
9.13.3
As shown in table 9-25, the port J pin functions can be switched, bit by bit, by changing the values
of OE2A to OE2H of motor control PWM timer PWOCR2 and PJDDR.
