PORTJ is an 8-bit wide, bi-directional port. The corre-
sponding data direction register is DDRJ. A ’1’ in DDRJ
configures the corresponding port pin as an input. A ’0’
in the DDRJ register configures the corresponding port
pin as an output. Reading PORTJ reads the status of
the pins, whereas writing to PORTJ will write to the
respective port latch.
PORTJ is a general purpose I/O port.
