Microcontroller is ATXMEGA128A1U in assembly

5.3 Write the interrupt service routine for TCCo timer/counter overflow. Perform the following operations in the service routine: (1) Check to see if the OCFIF flag is set, if yes, clear the OVFIF flag (bit 0) in the TCCO_INTFLAG register by storing the value oxo1 to it. Else, return from interrupt. (2) Decrement the global variable ovCnt (assumed it is assigned to r2o). (3) If ovcnt is not zero, return from interrupt. Else (a) load 5000 into TCCO_PER & TCCO_PER+1 (b) load 2000 into TCCO_CCA & TCCO_CCA+1 (c) return from interrupt. The name of the TCCo interrupt service routine is assumed to be TCCo_ISR. Solution: TCCo_ISR: 5.3 Write the interrupt service routine for TCCo timer/counter overflow.
