Configurable CBUS I/O Pin. Function of this pin is configured in the device internal
EEPROM. Factory default configuration is PWREN#. See CBUS Signal Options, Table
3.9. PWREN# should be used with a 10kΩ resistor pull up.
Configurable CBUS I/O Pin. Function of this pin is configured in the device internal
EEPROM. Factory default configuration is RXLED#. See CBUS Signal Options, Table 3.9.
Configurable CBUS I/O Pin. Function of this pin is configured in the device internal
EEPROM. Factory default configuration is TXLED#. See CBUS Signal Options, Table 3.9.
