# add HW interrupt support to core_rrv

- Source URL: https://github.com/FPGA-MAFIA/fpga_mafia/issues/437

The interrupt will start when one of the counters will reach a predefined value.

PR Title: fix issues we talked about csr

Description:
The contributor implemented an initial version that executes instructions once the timer interrupt is triggered. This approach ensures interrupts are processed when NOPs are absent, preventing loops. The implementation was tested with multiple timers using the comparison method for valid instructions. All relevant CSR updates are handled in the CSR module rather than software.

Commits (4):
1. Remove CSR check in ctrl and pass to CSR unit
2. Merge branch 'main' into core_rrv
3. Fix merge conflict issues
4. Fix timer interrupt handler
