Hi, guys

I added a multiplexer with 2 clocks at clock in of UART module

The question is , how can I control the multiplexer select pin?

The logic "high" seems can't be change by program

Thanks

You can use a one bit wide status register to provide a select signal.

Dear Bob

Thanks you reply so soon

But I cant understand how status register works and fit to what I need

Anywhere, thank you very much

Obviusly not my day... I meant to use a control register, not status.

Hi,

Although I have not been able to fully test the program,

probably adding a control register and control it from you program

will do what you want.

uint8_t value ;

value = Control_Reg_Read() ;

value = (value + 1) % 2 ;

Control_Reg_Write(value) ;
