dec Temp ; then count LEDS one up
sbis PIND,0x02 ; If (Port D, pin2 == 0)
ror Temp ; then rotate LEDS one right
sbis PIND,0x03 ; If (Port D, pin3 == 0)
rol Temp ; then rotate LEDS one left
sbis PIND,0x04 ; If (Port D, pin4 == 0)
com Temp ; then invert all LEDS
sbis PIND,0x05 ; If (Port D, pin5 == 0)
neg Temp ; then invert all LEDS and add 1
sbis PIND,0x06 ; If (Port D, pin6 == 0)
swap Temp ; then swap nibbles of LEDS
;**** Now wait a while to make LED changes visible.
