8.3. Hardware Flow Control (RTS and CTS)
To utilize the functionality of the RTS and CTS pins of the CP2105, the device must be configured to use hardware
flow control.
RTS, or Ready To Send, is an active-low output from the CP2105 and indicates to the external UART device that
the CP2105’s UART RX FIFO has not reached the watermark level of 191 bytes on the Enhanced Communication
interface or 63 bytes on the Standard Communication Interface and is ready to accept more data. When the
amount of data in the RX FIFO reaches the watermark, the CP2105 pulls RTS high to indicate to the external
UART device to stop sending data.
CTS, or Clear To Send, is an active-low input to the CP2105 and is used by the external UART device to indicate to
the CP2105 when the external UART device’s RX FIFO is getting full. The CP2105 will not send more than two
bytes of data once CTS is pulled high.
