(Operating Frequency 90MHz, with Baud rate of (9600 - 115200)bps. Please provide any information regarding it.

Hello @PK_1114,

I recommend looking into the UART Line Status Register. This register contains error bits that should provide you with a better insight of why the reception interrupt is not working properly on the LPC1768 specifically. Let me know if you identify an error.

BR,

Edwin.
