This is the value to be output on the receiver control lines (S0–S7) for this receiver
state. The value after reset = 0.
This is the time the FLEX chip IC 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 625 s. Valid values are 625 s (ST = $01) to 159.375 ms (ST = $FF). The value
after reset = 625 s.
These bit 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.
