4.2
A list of all the pins and signals are given in Table 4.2. The EEPROM configuration determines the signal
assigned to a pin.
Pins marked * are EEPROM selectable
Table 4.1 – List of the Modules Signals
Pins marked ** default to tri-stated inputs with an internal 75KΩ (approx.) pull up resistor to VCCIO.
Pin marked *** default to GPIO line with an internal 75KΩ pull down resistor to GND. Using the EEPROM
this pin can be enabled USBVCC mode instead of GPIO mode.
