#48244 - Some questions Responding to: ???'s previous message |
ok...i will try to make my questions as specific as possible.
1) the program starts from PWR_UP label and firstly calls 1.25ms timers to start and then set switch state and counters at 0 and Jmp to Main_LOOP, now here what does the formula: STATE_CNT EQU ($-STATE_TABLE)/2 shows.. like $ means the address of STATE_CNT subtrcting it with STATE TABLE ..and dividing it with 2 what does this means...and i think there will not be any problem if the code in the MAIN_LOOP label for legal state is not used or will there be? 2)Next i have gone through the CALL_TABLE but unable to understand its function, like how this rountine works...? |
