Question: What is the default configuration of UART pins in USB-Serial devices?
The following is the default configuration of UART pins in USB-Serial devices:
- Rx, which is an input is left floating for the other communicating peer to drive the pin.
- RTS, DTR, and Tx are output pins, and strong drive high (VCCIO/VDDD).
- DSR and CTS are inputs, with default configuration of Active Low, pulled up to VCCIO.
Note: In CY7C65213 the polarities of the UART pins (DCD, RI, RTS, CTS, DTR, and DSR) can be inverted using the USB-Serial Configuration Utility.
