6.5.24 ABxF Command 10H: Set Output

DESCRIPTION

Command 10H sets the states of the output lines and output LEDs "A" through "D."

DISCUSSION

This command sets the state of the digital output lines using a one-byte parameter, Output Status. The least significant nibble of the Output Status Byte determines the status of the outputs. The least significant bit of this nibble corresponds to Output A. The most significant bit of this nibble corresponds to Output D. The most significant nibble of the Output Status Byte is reserved and should be set to 0H. An output bit set to one (1) turns the corresponding LED on, and closes the electronic switch of the output, allowing current to flow through the output circuit. An output bit reset to zero turns the corresponding LED off, and open the electronic switch in the output circuit. The following chart shows the hex values for all combinations of output status bytes. To reset all output bits, issue the command with 00H for the output status byte.
