RECEIVER CONTROL CONFIGURATION PACKETS
These packets allow the host to configure what setting is applied to the receiver control lines
SO
-
S7
, how long to
apply the setting, and when to read the value of the
LOBAT
input pin. For a more detailed description of how the
S5T8701 uses these settings see
"
Receiver Control
"
on page 55. The S5T8701 defines 12 different receiver
control settings. Proper operation is not guaranteed if these settings are changed when decoding is enabled (i.e.
the
ON
bit in the Control Packet is set). The IDs for these packets range from 16 to 27 (decimal).

LBC:
Low Battery Check. If this bit is set, the S5T8701 will check the status of the LOBAT port just before
leaving this receiver state. (value after reset=0)
CLS:
Control Line Setting. This is the value to be output on the receiver control lines (S0 - S7) for this
receiver state. (value after reset=0)
ST:
Step Time. This is the time the S5T8701 is to keep the receiver off before applying the first warm
up state's receiver control value to the receiver control lines. The setting is in steps of 625us. Valid
values are 625us (
ST
=01) to 159.375ms (
ST
=FF in hexadecimal). (value after reset=625us)
