A single binary-encoded value where each bit determines whether _STATE, _DIRECTION or _ANALOG_ENABLE writes affect that bit of digital I/O. 0=Default=Affected, 1=Ignored.

• Data type: UINT32  (type index = 1)
• Readable and writable
• Default value: 0

Constant	Value
Affected	0
Ignored	1

Read or write the direction of all digital I/O in a single binary-encoded value. 0=Input and 1=Output. Writes are filtered by the value in DIO_INHIBIT.

• Data type: UINT32  (type index = 1)
• Readable and writable

Constant	Value
Input	0
Output	1

Read or write the state of all digital I/O in a single binary-encoded value. 0=Low AND 1=High. Does not configure direction. A read of an output returns the current logic level on the terminal, not necessarily the output state written. Writes are filtered by the value in DIO_INHIBIT.
