UART3 RX

Hi,

 

 I try to get UART3 on LPC4088 working, already got UART TX working well, but RX stops in RBR register. I checked the Rx pin with the oscilloscope and there is some data incoming. I configured UART with 115200Baud at 120MHz CCLK so I think the Baud isn't the problem.

 

When I compile the program and step into it the LSR register get the value 0x60 (0b0110 0000) and the program stuck in the while loop, so I obviously received a framing error, parity error or break interrupt. I attached some simple UART config.

I use Hterm as Terminal to send to the MCU

 

Best Tim
