... CP2103 reset until device configuration during USB Enumeration is complete. The CP2103 exits the Suspend mode when any of the following events occurs: (1) Resume signaling is detected or generated, (2) a USB Reset signal is detected, or (3) a device reset occurs. Upon exit from Suspend mode, the SUSPEND and SUSPEND signals are de-asserted ...

... CP2103 5. Asynchronous Serial Data Bus (UART) Interface The CP2103 UART interface consists of the TX (transmit) and RX (receive) data signals as well as the RTS, CTS, DSR, DTR, DCD, and RI control signals. The UART supports RTS/CTS, DSR/DTR, and X-On/X-Off handshaking. The UART can be programmed to support a variety of data formats and baud rates. If the Virtual COM Port drivers are used, the data format and baud rate are set during COM port configuration on the PC ...
