6.4.25 ABxS Command 11H: Input Status

DESCRIPTION

Command 11H returns the status of user inputs.

DISCUSSION

This command interrogates the state of the user input lines and return a one-byte parameter, Input Status. The least significant nibble of the Input Status Byte is determined by the status of the outputs. The least significant bit of this nibble corresponds to Input A. The most significant bit of this nibble corresponds to input D. The most significant nibble of the Input Status Byte is set to 0H. A closed circuit in one of the user inputs sets the corresponding user input bit to one, turning the corresponding LED on. An open circuit in one of the user inputs sets the corresponding User Input bit to zero, turning off the corresponding LED. The following chart shows all of the valid hex values for the Input Status bytes.
