UART1 practical question

Started by Milos Prokic September 15, 2004
Hi everyone,

I'm using LPC2106. I want to implement an application using UART1, and my
question is whether the UART1 requires me to select all of 8 pins through
pin select block, or I can just select the TX, RX, RTS and CTS leaving DSR,
DTR, DCD and RI for GPIO.

Thanks a million,

m.

I'm using an LPC2129 and have not had any problems using just the
same four pins for uart1 that you are asking about. Moreover, I'm
also using two of the 8 uart1 pins as external interrupts so I should
think that you won't encounter any problems with using the remaining
pins as GPIO.

Mal, thanks for the info!

Cheers,

m.
