3.2.3 CO2064 and CO2128/CO2144 Pin Configuration
On power-up, all IO ports (PIOA, PIOB, PIOC) assume general purpose input pins functionality
whose state may be inspected or driven individually by software. Based on the application, the
ports are reconfigured by software to assume the applicable functionality as part of the power -
up system setup routine. The selection is determined by tying the following pins to either VDD
(‗1‘) or GND (‗0) via a pull-up or pull-down resistor, respectively, as detailed in Table 3-4.
