Host-to-Decoder Packet Descriptions
CONTROL LINE SETTING (CLS)
This is the value to be output on the receiver control lines (S0âS7) for this receiver
state. The value after reset = 0.
STEP TIME (ST)
This is the time the FLEX chip IC is to keep the receiver off before applying the first
warm up stateâs receiver control value to the receiver control lines. The setting is in
steps of 625 µs. Valid values are 625 µs (ST = $01) to 159.375 ms (ST = $FF). The value
after reset = 625 µs.
