hi;
the nested djnz loop seems to fail if no.of
loop counts is on 256 boundary.if i put 100h
200h etc it shall execute 256 more transfers.
may be one should add:
mov r6,#high(loop_count)
mov r7,#low(loop_count)
cjne r7,#00,go_to_loop
inc r6
go_to_loop:
;add loop
of course one assumes loop_count!=00

your comments awaited
