The architecture specifies specification exceptions for all
|
|
|
ae23c9 |
unavailable subcodes.
|
|
|
ae23c9 |
|
|
|
ae23c9 |
The presence of subcodes is indicated by checking some query subcode.
|
|
|
ae23c9 |
For example 6 will indicate that 3-6 are available. So future systems
|
|
|
ae23c9 |
might call new subcodes to check for new features. This should not
|
|
|
ae23c9 |
trigger a hw error, instead we return the architectured specification
|
|
|
ae23c9 |
exception.
