Output Structure
Open-drain output
Push-pull output
When the I/O port is used as input, the weakly high sourcing PMOS can be used as pull-up. Open drain
can be used if the pull-up is not required and let the external driver to drive the pin. Please note that a
floating pad could cause more power consumption since the noise could interfere with the circuit and
cause the input to toggle. A ‘1’ needs to be written to port first before reading the input data from the I/O
pin, otherwise, the pin will always be stuck at ‘0’. If the PMOS is used as pull-up, care should be taken to
avoid the constant power drain by DC path between pull-up and external circuit.

PRT11[7..0], PRT14[7..0], PRT15[7..0] and PRT17[7..0] share pads with SEG[8..39]. The function of the
pins is selected by mask option MO_LIO11, MO_LIO14, MO_LIO15, MO_LIO17 respectively as shown
