PACKET COMMUNICATION INITIATED BY THE FLEX DECODER IC
Refer to figure 7 on page 12. When the S5T8701 has a packet for the host to read, the following occurs:
1.
The S5T8701 drives the
READY
pin low.
2.
If the S5T8701 is not already selected, the host selects the S5T8701 by driving the
SS
pin low.
3.
The host receives (and sends) a 32-bit packet.
4.
The host de-selects the S5T8701 by driving the
SS
pin high (optional).

Figure 7: Typical Multiple Packet Communications Initiated by the FLEX decoder IC
When the host is reading a packet from the S5T8701, it must send a valid packet to the S5T8701. If the host has
no data to send, it is suggested that the host send a Checksum Packet with all of the data bits set to 0 in order to
avoid disabling the S5T8701. See "Checksum Packet" on page 16 for more details on enabling and disabling the
S5T8701.
The following figure illustrates that it is not necessary to de-select the S5T8701 between packets then the packets
are initiated by the S5T8701.
