CCS PIC C: What is the difference between #INT_TIMER0 and #INT_RTCC?
I have always treated them interchangeably (one and the same thing).  Here's what CCS compiler manual says about this:


  #INT_RTCC ----- Timer 0 (RTCC) overflow
  #INT_TIMER0 -- Timer 0 (RTCC) overflow


From the header file for PIC18F4550.h 1

#define INT_RTCC                  0xF220
#define INT_TIMER0                0xF220


1 Nothing particular about PIC18F4550.  I'm using it as an example, because it's nearest to me, because it's in the project that I'm currently working on.
