CYUSBS234 QUICK START GUIDE
Note: By default, the SCB configuration jumpers are set for the USB-UART bridge as shown above. Refer to the
Table 3-1 in the kit guide for additional information on default jumper settings.
Kit operation: The CY7C65211, USB-Serial bridge controller can be configured as an USB-UART bridge,
an USB-I2C bridge, or an USB-SPI bridge. As an USB-UART bridge, data is transmitted from USB to UART (TXD).
TXD-RXD loop back connection enables the data to be fed back to the UART (RXD) to USB and is displayed
on the Tera Term window. The CY7C65211 controller also supports battery charger detection and configurable
CapSense functionality, providing best-in-class signal-to-noise ratio (SNR) and water-tolerance
