1. what is the difference between symbol A and ACC used for accumulator. 2. when i use (in assembly)PUSH A, i get error. PUSH ACC does not give me error. 3. in the debug environment i do not understand what does following register do or what does it stand for. pl explain it to me. a. Sp_max b. Auxr_1 c. states 4. when i used " SRF p0= 0x08" inside main function i get error. when i declare it globally its okay. is this the restriction that declaration with sfr must be outside the main. 5. can we use PUSH and POP command with any register or there are some speciific register with which it works. Thanks for help
