The following table shows the +MIOD parameters.
Table 3-106: +MIOD Parameters
Description
Selected pins for the action invoked. This is a binary vector in which each bit points to
pin number. Vector size is 8.
0 Not selected
1 Selected pin
GPIO pin operation mode.
0 Pin will be defined as Output (default value HIGH)
1 Pin will be defined as Input
This is a binary vector in which each bit shows the physical value of pin. Data vector
size is 8.
0 Physical low signal.
1 Physical high signal.
The default value:
On Power Up - as previously saved in FLEX bytes.
Before set command first used with and =0, or after +MIOD
without and before +MIOD command used - 1.
Note: GPIO mode will not be saved in case of a power cut.
Error using MIOD commands
1. In case is input and is supplied, a +CME ERROR: "operation not
allowed" error will be issued and no action will be taken.
2. When missing one of the mandatory Parameters the following error will be returned:
+CME ERROR:" Invalid number of Parameters".
3. If pin selection or data vector contain digits different from "0" or "1" an error will be
returned.
+CME ERROR:" numeric parameter out of bounds".
