Coding of PNIO status
The PNIO status is a 32 bit unsigned value. It is composed of 4 byte values, which define the meaning of the status. For positive responses PNIO status has a value of zero.
| Bit | Meaning |
|---|---|
| 24-31 | ErrorCode |
| 16-23 | ErrorDecode |
| 8-15 | ErrorCode1 |
| 0-7 | ErrorCode2 |
