4.2 Signal Descriptions
Pins marked * are EEPROM selectable
Pin # Pin Name
Table 4.1 : UM232H 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.
