UART Module

Category

Functional

Function

UART start condition not detected when transitioning to STANDBY1 Mode

Description

After servicing an asynchronous fast clock request that was initiated by a UART transmission while the device was in STANDBY1 mode, the device will return to STANDBY1 mode. If another UART transmission begins during the transition back to STANDBY1 mode, the data is not correctly detected and received by the device.

Workaround

Use STANDBY0 mode or higher low power mode when expecting repeated UART start conditions.
