Hi all,

Is normal that when I call the function Chip_UART_IntEnable(LPC_USART0, UART_INTEN_RXRDY) will produce an inmediate interrupt although don't exist data in serial port?

I am using LPC812, LPCXpresso v7.5.0 [Build 254] [2014-10-31] and LPC8xx UART driver.

Please, can anybody help me?

Many thanks in advance
