Table 3.3 Interface Pins
Notes:
1. When used in Input Mode, the input pins are pulled to VCCIO via internal 75kΩ (approx.) resistors.
3.2 Interface Selection
The FT311D has multiple interfaces available for connecting to external devices. The resources available
are GPIO, UART, PWM, I2C(Master), SPI(Slave) and SPI(Master). The selection of what interface the user
requires is configured using the CNFG0, CNFG1 and CNFG2 input pins as per table 3.4.
