FEEX^TM ALPHANUMERIC DECODER II
S5T8702
PART ID PACKET
The Part ID Packet is sent by the S5T8702 whenever the S5T8702 is disabled due to the checksum feature. See
"Checksum Packet" on page 16 for a description of the checksum feature. Since the S5T8702 is disabled after
reset, this is the first packet that will be received by the host after reset. The ID of the Part ID Packet is 285
(decimal).
