+MIOD, Motorola I/O Define

This command defines the G24-L 8 GPIO pins configuration. The feature is flex enabled or disabled.

This command is a basic command.

The feature is active by default, however, changing the FLEX can eliminate it.

Note: When using the GPIO lines feature, lines should not be connected directly to ground, a resistor must be used. This is applicable when changing an I/O from input to output.

Command

Set	AT+MIOD=<Pin	OK	The set command defines the behavior
	selection>,<Mode>	or:	mode of each selected IO pin.
	[,<Data vector>]	+CME ERROR: <err>	The G24-L saves the new setting in
			flex. The selected pins are affected.
			Validity check of all parameters will be
			done and appropriate standard error
			will be issued.
			In case of legal parameters the new
			configuration is set. If <Data vector>
			doesn't supply and new <Mode> is
			output a line will care physical high
			signal. In case <Data vector> is supply
			and includes values of input pins, those
			values will be ignored. In case
			<Mode> is input and <Data vector> is
			supply, an error will be issued
			"Operation not allowed". No action
			will be done.
