Auto Baud rate interrupt not occurring

Hi,

As we mentioned earlier, we are using LPC4357 and UART1 is connected to an embedded Ethernet module. We have set UART1 baud rate to 115200 and enabled the auto baud rate capability. To test the auto baud rate capability, we have set the baud rate of ethernet module UART to 57600. We thought in this case, LPC automatically lowers UART1 baud rate to 57600 and auto baud rate interrupt should occur. Auto baud rate interrupt is not occurring, so we are not receiving correctly. Any idea why auto baud rate interrupt is not occurring? When both side baud rate is set to  115200 or 57600, communication works properly.

Thanks
