I am not sure that the 1uF capacitor works. After going through the ATMEL data sheet I am unable to tell what the recommended capacitor value should be.

Actually, the code that I assembled is a loop as follows .... any help would be appreciated:


start:
mov p0,#h'F0
mov p1,#h'F0
loop:
mov p0,#h'F0
mov p1,#h'F0
sjmp loop
;
.segment .memory
.memory
.org h'20
.end start
