Hi

How to explain (rs232_base+1) ,Means TXDATA's address?

--- Quote End ---

Micio82 described that it worked for him. At least partially. He used (rs232_base+1) for TXDATA-address.

but in my code I am using:

--- Quote Start ---

IOADDR_ALTERA_AVALON_UART_TXDATA(RS232_BASE )

--- Quote End ---

which works fine and I am thinking which should be the correct way to get the TXDATA-address.

We (micio82 and me) thought it was a bit strange that (rs232_base+1) partially worked. Therefore was my question, did you make the same observation?
