LINFlexDx works in UART mode. Once its timeout INTR is triggered, the status bit of LINFlexDx_UARTSR[TO] won't be reset which is unexpected to me. This causes the further timeout INTR keeps firing.
Hi,
As per the RM UARTSR[TO] is cleared by software, writing 1 to this bit.
The GCR[SR] bit can be used to reset the receiver fsm to Idle state in case of UART TIMEOUT for UART reception, depending on the application, in both buffer and FIFO mode.
