Detailed Errata Descriptions 2.1 CP2103_E101 – Dynamic Suspend Error Description of Errata Dynamic Suspend is an optional feature that, when enabled, allows for GPIO pins or modem signals to assume a pre-programmed state during USB SUSPEND, and then return to their pre-SUSPEND states on exit of USB SUSPEND. The potentially affected pins are RXD, CTS, DSR, DCD, RI, and any GPIO pin configured as an input. If the Dynamic Suspend feature is enabled, the pin state may switch from Input mode to Output mode and drive a logic ‘0’ if a logic ‘0’ was read on the corresponding pin upon entry into SUSPEND. Affected Conditions / Impacts On resume from USB SUSPEND, a pin previously configured as an input can switch to an output and drive a logic ‘0’. The pin will remain an output until either power is cycled or the device receives a reset from the /RST pin. Workaround There is currently no workaround for this issue. Resolution There is currently no planned resolution for this issue. silabs.com | Smart. Connected. Energy-friendly.
