Input/Output Ports
7.20 Port J (PJ0 through PJ7)
The port J is a general-purpose, 8-bit input/output port. For this port, inputs and outputs can be specified in units
of bits by using the control register PJCR and the function register PJFC1. A reset allows all bits of the output
latch PJ to be set to "1," all bits of PJCR to be cleared to "0," and the port J to be put in input mode.
Input is disabled right after reset. To enable input, set the corresponding bit of PJIE to “1”.
Besides the port function, the port J performs other functions: PJ0 and PJ1 input a 16-bit timer PJ2 through PJ7
input external interrupts.
