Function of this pin is configured in the device MTP memory. The default configuration is RXLED#. See CBUS Signal Options, Table 3.7. 5 CBUS2 I/O Configurable CBUS I/O Pin. Function of this pin is configured in the device MTP memory. The default configuration is TXLED#. See CBUS Signal Options, Table 3.7. 14 CBUS3 I/O Configurable CBUS I/O Pin. Function of this pin is configured in the device MTP memory. The default configuration is SLEEP#. See CBUS Signal Options, Table 3.7. Table 3.3 UART Interface and CBUS Group (see note 1) Notes: 1. When used in Input Mode, the input pins are pulled to VCCIO via internal 75kΩ (approx) resistors. These pins can be programmed to gently pull low during USB suspend (PWREN# = “1”) by setting an option in the MTP memory. Copyright © 2015 Future Technology Devices International Limited 8
