Algorithm for pulsed slots

The following pseudo-code describes how the anticollision could be implemented on the
VCD, using recursive functions.
function push (mask, address); pushes on private stack
function pop (mask, address); pops from private stack
function pulse_next_pause; generates a power pulse
function store(LRI64_UID); stores LRI64_UID
function poll_loop (sub_address_size as integer)
last stored collision
end poll_loop
main_cycle:
end_main_cycle
pop (mask, address)
mask = address & mask; generates new mask
mode = anticollision
send_Request (Request_cmd, mode, mask length, mask value)
for sub_address = 0 to (2^sub_address_size - 1)
if stack_not_empty ; if some collisions have been detected and
mask = null
address = null
push (mask, address)
poll_loop(sub_address_size)
pulse_next_pause
if no_collision_is_detected ; LRI64 is inventoried
next sub_address
then
endif
then
else ; remember a collision was detected
endif
poll_loop (sub_address_size); recursively to process the
