DECODER-TO-HOST PACKET DESCRIPTIONS
The following sections describe the packets of information that will be sent from the S5T8701 to the host. In all
cases the packets are sent MSB first (bit 7 of byte 3 = bit 31 of the packet = MSB). The S5T8701 decides what
data should be sent to the host. If the S5T8701 is disabled through the checksum feature (see "Checksum
Packet" on page 16 for a description of the checksum feature) the Part ID Packet will be sent. Data Packets
relating to data received over the air are buffered in the 32 packet transmit buffer. The Data packets include
Block Information Word Packets, Address Packets, Vector Packets, and Message Packets.
If the S5T8701 is enabled and a receiver shutdown packet is pending, the receiver shutdown packet will be sent.
If there is no receiver shutdown packet pending, but there is a roaming status packet pending, the roaming status
packet will be sent. If neither the receiver shutdown packet nor the roaming status packet is pending and there is
data in the transmit buffer, a packet from the transmit buffer will be sent. Otherwise, the S5T8701 will send the
Status Packet (which is not buffered). In the event of a buffer overflow, the S5T8701 will automatically stop
decoding and clear the buffer.
It is recommended that the Host be designed to empty the FIFO buffer every block with enough time left over to
read a status packet. This would ensure that any applicable Status Packet would be received within 1 block of the
new status being available.
