Enable or disable RI or TI individually

perline chee

Hi,

I am using 8051 family's uController(AT89C55WD).
May I know is there a way to enable or disable transmit(TI) and receive(RI) interrupt individualy?

Pls advice...
Thank you.

regards,

Parents

    You quoted me as saying, "softcore it might not be that hard" - but you missed the important part of it!

    What I actually said was (emphasis added), "if one were working with a softcore it might not be that hard..."

    You are not working with a softcore - you are using a standard, off-the-shelf, physical chip - the AT89C55WD, you said.

    For a standard 8051 (including the AT89C55WD), the original advice stands: You can not separately enable/disable TI and RI.

    Although, as originally noted, you can disable the receiver...
