LPC3250 High Speed UART issue

Hi guys,

I need to understand why the HSUART of LPC doesn't change the parameteres of STOP BIT, PARiTY, WORD LENGTH?

It's set 8N1 and I need change it for other values ... When I read the driver lpc32xx-hsuart.c I saw it set always 8N1, and I couldn't change (even if I set another value by code, it keep the old value 8N1).

These UARTs can't change the parametes? Why is it happen?

Thanks so much for any reply.

Hi Henrique,

According with section 20.2 of LPC32x0 and LPC32x0/01 User manual:

The three 14-clock UARTs only support the communications format of (8N1) 8-bit data word length, 1-stop bit, no parity, and no flow control.

Therefore, the format configuration is just available on the Standard UARTs.

Hope this will be useful for you.
Best regards!
/Carlos
