ISR in SoC

Started by star...@gmail.com October 3, 2008
Hi all,
My name is Ravi. I am working on system integration and testing.
I am using SDCC compiler for my C code compilation. I have different
peripheral module like i2c, spi, uart, memory controller, lcd.
Inside ISR, based on status of interrupt controller i am setting
flags, and based on these flag i want to call some functions to
reconfigure the peripherals. So where do i need to write those
functions and from where should i call them.  Can I  call these
function in main.

please reply.
