CBUS3
I/O
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.
21
CBUS1
I/O
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.
22
CBUS0
I/O
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.
Table 3.8 UART Interface and CBUS Group (see note 3)
Notes:
1. The minimum operating voltage VCC must be +4.0V (could use VBUS=+5V) when using the
internal clock generator. Operation at +3.3V is possible using an external crystal oscillator.
2. For details on how to use an external crystal, ceramic resonator, or oscillator with the FT232R,
please refer to Section 7.6.
3. When used in Input Mode, the input pins are pulled to VCCIO via internal 200kΩ resistors. These
pins can be programmed to gently pull low during USB suspend (PWREN# = “1”) by setting an
option in the internal EEPROM.
