I have a problem with MCU ADUC7126.
I config pin P4.0 as SIN1 and P4.1 as SOUT1 in GP4CON:
It works, I see recieved and transmit UART1 data.
When I config pin P2.3 as AE (external memory) in GP2CON:
I read/write external memory data, but I doesn`t recieved data on UART1.
Could you tell me please, what I do wrong?
