With the GPIO_CFG0 signal on the rear I/O module an active COMB or GPIO interface can be
selected.
Table 2-17: GPIO Signal Description
GPIO SIGNAL
GPIO_CFG0 0 = GPIO
1 = COMB
Note ...
The default value is 1 if pin D4 is not connected (pull-up resistor to 3.3V on
CP3002). If the pin is connected, the default value depends on the rear I/O
module. If the pin is driven by the rear I/O module, it must be considered that
the CP3002 tolerates only 3.3 V signaling on this input.
