Hi friends , I wrote a code for driving the M48T86 in Assembly but the problem still reains and the chip doesn't respond. Here is my code.

;-------------------------------------------
ORG 000
JMP MAIN
;BUS EQU 80H;P0
;RCL EQU 94H;P1.4
;RST EQU B1H;P3.1
;IRQ EQU B2H;P3.2
;DSB EQU B7H;P3.7
;RW EQU B6H;P3.6
;AS EQU B4H;P3.4
;E EQU B3H;P3.3

The lines at the beginning are commented because Franklin doesn't accept the , so I commented these lines and use the addresses directly.

please help.
thanks
