Roaming Decoder II
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 KS8701 uses these settings see
“
Receiver Control
”
on page 55. The KS8701 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 KS8701 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 KS8701 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)
