NOTE:
None of the input lines have internal pull-up or pull-down resistors. The input lines must be in a known state
(either GND or V
input lines are never floating, either by using external resistors, by tying the lines directly to GND or V
by use of other circuits to control the line state.

The decoder has eight data lines, D0 through D7. These lines will reproduce the
state of the encoder’s data lines upon reception of a valid packet.
This line is used to select the baud rate of the
serial data stream. The state of the line allows
the selection of one of two possible baud
rates, as shown in the adjacent table.
The baud rate must be set before power-up. The decoder will not recognize any
change in the baud rate setting after it is on.
When this line is taken high along with the LEARN line, the decoder will enter
Send Copy Mode and output the User Data on the KEY_OUT line. When taken
high with the CREATE_KEY line at power-up, Send Copy Mode will be disabled.
These lines are connected to ground.
This line is used to input the User Data from another decoder.
When this line is taken high along with the LEARN line, the decoder will enter
Create Mode and create a key and encoder ID. It will then send these to the
encoder through the KEY_OUT line. When taken high with the SEND_COPY line
at power-up, Send Copy Mode will be disabled.
When the SEND_COPY and LEARN lines are taken high at the same time, the
decoder will output the User Data on this line. This line will also output the
transmitter identity upon reception of the first valid packet of each session.
This line will activate when a valid transmission is received, when the decoder
enters Learn Mode, Get Key Mode, Create Key Mode, or Send Copy Mode, and
when the memory is cleared. This allows for the connection of a LED to indicate
to the user that these events have taken or are taking place.
When this line goes high and is then pulled low, the decoder will enter Learn
Mode to accept permissions from an encoder and store it in memory. If it is held
high for ten seconds, the decoder will clear all User Data from memory. If it goes
high with SEND_COPY or CREATE_KEY, then the decoder will enter Send
Copy Mode or Create Key Mode, respectively.
This line accepts serial data from the encoder, usually via a wireless link.
These lines are connected to the positive power supply.
