#129597 - Set the STA bit to initiate the vector Responding to: ???'s previous message |
Hi Charles,
I think I figured out the problem. The interrupt vector should be at 0x3b only. The code stops at "ljmp SMBus_ISR" after SETB STA. Rather the start bit has to be set so that the code goes to the SMBus interrupt vector. After the SMBus is initialized, set the STA bit. Set the breakpoint at "ljmp SMBus_ISR" and you will find the code stopping at "ljmp SMBus_ISR" . Problem solved. Thanks for your help. I am still having problems with communicating with CODEC.I will have to look more itno the code before I post any questions. Thanks |
