used as GPIO (General Purpose Input Output). The GPIO of W7100A is shown in the Figure
below. The output driving voltage of GPIO is 0V or 3.3V according to the Px_PD/PU SFR value.
All other instructions read from a port exclusively through the port pins. All ports pin can be
P0_PD(0xE3): GPIO0 Pull-down register, the value ‘1’ pull-down the related pin.
P1_PD(0xE4): GPIO1 Pull-down register, the value ‘1’ pull-down the related pin.
P2_PD(0xE5): GPIO2 Pull-down register, the value ‘1’ pull-down the related pin.
