Fourteen bidirectional input-output (I/O) pins, two input pins, and six
output pins form three parallel ports.
When using the 28-pin package versions of the MC68HC908MR8, set
the data direction register bits in DDRA such that bits 6, 5, and 4 are
written to a logic 1 (along with any other output bits on PORTA). Setting
PORTA’s data direction register bits 6, 5, and 4 will terminate the input
buffers on that port.
Connect any unused I/O pins to an appropriate logic level, either V

do not require termination for proper operation, termination reduces
excess current consumption and the possibility of electrostatic damage.
