When the host receives a Message Packet with the Message Continued Flag
"
C
"
= 0, it will send two All
Frame Mode Packets to the S5T8701 with the
"
DAF
" bit = 1. The two packets decrement the count for the
first fragment and the last fragment. This decrements the all frame counter to zero, if no other fragmented
messages, temporary addresses are pending and the
FAF
bit is clear in the All Frame Mode Register, the
S5T8701 returns to normal operation.
The above process must be repeated for each occurrence of a fragmented message. The host must keep
track of the number of fragmented messages being decoded and insure the all frame mode counter
decrements after each fragment or after each fragmented message.
