SETB 90H ; THIS SETS ALL THE PORT PINS ON BANK 1 TO OUTPUT
NO, it does not! it sets p1.0 ONLY. Do not confuse bit address and byte address, they look the same but are not. Also "BANK 1" is something completely different, you refer to port 1. Erik Thankyou, but how, then, do you write to the other port pins? |
