Code:

0100 db b3              loop:   in a, (0xb3)       
0102 c3 00 01                   jp loop     ; sorry, can't assemble relative backward jumps in my head

so, this should do it - you should see pulses on the left end of R24. However, the loop is probably so fast that you will not see a clean reset on the other side.
