KS8701
PART ID PACKET
“Checksum Packet” on page 16 for a description of the checksum feature. Since the KS8701 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 255
(decimal).
Table 29: Part ID Packet Bit Assignments
The Part ID Packet is sent by the KS8701 whenever the KS8701 is disabled due to the checksum feature. See
MDL: Model. This identifies the FLEX decoder model. Current value is 0.
