LOOP1:  MOV COUNT1, #5H
        
LOOP2:  CODE...
LOOP3:  CODE... 
        DJNZ COUNT1, LOOP2
        (CONDITION)
        JMP  LOOP1 

Please be forwarned that though this will do what you want, it is an endless loop. You need something more to break the loop - like check for some (CONDITION) before looping to LOOP1. Else only a RESET can get break the looooooo...p.

Also if you have no spare IRAM space to allocate for COUNT1, just use any free register R0 to R7 or B register.
