Twelve bidirectional input/output (I/O) pins form two parallel ports in the 32-pin
low-profile quad flat pack (LQFP). All I/O pins are programmable as inputs or
outputs. Port A bits PTA6–PTA1 have keyboard wakeup interrupts and internal
pullup resistors.
Connect any unused I/O pins to an appropriate logic level, either V
Although the I/O ports do not require termination for proper operation, termination
reduces excess current consumption and the possibility of electrostatic damage.
