Hi
Is there a strict timing requirement when I use uart for interrupt sending to call the SDK's LPUART_SetIntMode(LPUART_Type * base, lpuart_interrupt_t intSrc, bool enable) and void LPUART_SetTransmitterCmd(LPUART_Type * base, bool enable) enables?
I'm not sure about the requirement of timing in ISR Uart, but I refer you to use Uart's callback function when the interrupt handler is done to change your setting.
