GPIO Configuration ** Format: A(CCU)

Type: Read-Only (Optionally Read-write using CMD_PROP_VALUE_INSERT)
An array of structures which contain the following fields:
- C: GPIO Number
- C: GPIO Configuration Flags
- U: Human-readable GPIO name
GPIOs which do not have a corresponding entry are not supported.
The configuration parameter contains the configuration flags for the
GPIO:
```
  0   1   2   3   4   5   6   7
```
```
+---+---+---+---+---+---+---+---+
```
```
|DIR|PUP|PDN|TRIGGER|  RESERVED |
```
```
+---+---+---+---+---+---+---+---+
```
```
        |O/D|
```
```
        +---+
```
- DIR: Pin direction. Clear (0) for input, set (1) for output.
- PUP: Pull-up enabled flag.
- PDN/O/D: Flag meaning depends on pin direction:
```
*   Input: Pull-down enabled.
```
```
*   Output: Output is an open-drain.
```
- TRIGGER: Enumeration describing how pin changes generate

asynchronous notification commands (TBD) from the NCP to the host.

```
*   0: Feature disabled for this pin
```
```
*   1: Trigger on falling edge
```
```
*   2: Trigger on rising edge
```
```
*   3: Trigger on level change
```
- RESERVED: Bits reserved for future use. Always cleared to zero
```
and ignored when read.
```
As an optional feature, the configuration of individual pins may be
modified using the CMD_PROP_VALUE_INSERT command. Only the GPIO
number and flags fields MUST be present, the GPIO name (if present)
would be ignored. This command can only be used to modify the
configuration of GPIOs which are already exposed—it cannot be used
by the host to add additional GPIOs. */
