Port J interrupt flag—
If the associated interrupt enable bit is set this flag asserts after a valid active edge was detected on the related pin
(see
polarity select register.
Writing a logic “1” to the corresponding bit field clears the flag.
1 Active edge on the associated bit has occurred (an interrupt will occur if the associated enable bit is set)
0 No active edge occurred
Port AD general-purpose input/output data—Data Register
When not used with an alternative signal, the associated pin can be used as general-purpose I/O. In
general-purpose output mode the port data register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port data register bit, otherwise the
buffered pin input state is read if the digital input buffers are enabled
