UART tx and rx interrupt

Question asked by RAZ on Jul 26, 2009

Hi,

 

   I am suing SHARC 21369 processor. I want to use the UART Transmit and receive interrupt to send and receive messages. I have gone through the UART echo back example.

 

The echo back example uses only receive interrupt. I have gone through the hardware refrence manual and I am a bit confuse on how to enable and use both transmit and receive interrupts.

 

The uart receive interrupt is assigned to P13 using the following

 

*pPICR2 &= ~(0x3E0);  

//Sets the UART0 receive interrupt to P13

 

Do I need to assign UART0 transmit interrupt to say P14?  I will be grateful if anyone could provide me some information or example code.

 

 

         Cheers,

         RAZ.
