Hi There,
I'm a newbie in the field of 8051 programming. So my way of thinking might be totally wrong.
However, this is the case:
I have a system for which I have to write some program. I can download the program into the external RAM of the system using the firmware available in ROM. The main processor of the system is a 80C32 microcontroller. Now I want to make use of the serial interrupt. When a serial interrupt occurs, the control will jump to 0023h (in IRAM a presume). Now I have an interrupt routine stored in external RAM. How can I specify a jump at 0023h of IRAM to this routine in XRAM?
I use assembly to code my programs.
