SETTING NUMBER (s)
These bits define the receiver control setting for which this packet’s values are to be
applied. The following truth table shows the names of each of the values for “s” that
apply to this packet.
Table B-19 Setting Number Bit Definitions
s₃ s₂ s₁ s_{0 Setting Name}
0 1 1 1 1600 sps Sync
1 0 0 0 3200 sps Data
1 0 0 1 1600 sps Data
LOW BATTERY CHECK (LBC)
If this bit is set, the FLEX chip IC will check the status of the LOBAT port just before
leaving this receiver state. The value after reset = 0.
CONTROL LINE SETTING (CLS)
This is the value to be output on the receiver control lines (S0–S7) for this receiver
state. The value after reset = 0.
