I am trying to use MPU_STIM_INTRQ to manually generate interrupt for debugging porpuse. However, I found it can only fire once just after 7612 initialization. Thereafter, writing MPU_STIM_INTRQ is not effective.
Here is my pseudo codes for triggering the interrupt
write 98 4B 80
write 98 40 e6
read 98 47 2
write 98 49 80
Thank you in advance for your help
