#185529 - Check the CJNE instruction... Responding to: ???'s previous message |
You can use the carry flag to test if A > 4...
;Instead of IF A>=0x03 SETB GAIN_ERROR RET ENDIF ;I have written CJNE A, #0x03, INC_A_1 SETB GAIN_ERROR RET INC_A_1 ; I just have to hope that there is no error above 4 ;Check the carry flag here. If A > 3 it will be clear ;and for IF A=#0x00 SETB GAIN_ERROR RET ENDIF ; I made a simple JZ opperation JZ ERR |
