CHAPTER 10—MODE SENSE (1Ah)
10.2 WHAT YOU SEND TO THE LIBRARY
DBD (Disable Block Descriptors) – Byte 01, Bit 3
The library ignores this bit.
PC (Page Control) – Byte 02, Bits 7 and 6
This field defines the type of parameters that are to be returned for the MODE
SENSE command. Specify one of the following values:
0 (00b) – Current values Indicates that the library should return the current
parameter values. The current values returned are:
The parameters set in the last successful MODE SELECT command.
The saved values, if a MODE SELECT command has not been executed since
the last power-on or reset.
The default values, if saved values are not available.
1 (01b) – Changeable values Indicates that the library should return the
changeable parameter masks. The pages you request are returned and indicate
which parameters you can change. All bits of parameters that you can change
are set to 1. All bits of parameters that you cannot change are set to 0. The Page
Code and Parameter List Length fields contain actual values.
Note: Before issuing a MODE SELECT command, issue a MODE SENSE
command with the PC field set to 1 and the Page Code field set to 3Fh.
This will allow you to determine the supported pages, the changeable
parameters within the pages, and the supported length of each page.
2 (10b) – Default values Indicates that the library should return the default
values. The pages you request are returned, with each supported parameter
set to its default value. Parameters not supported by the library are set to 0.
3 (11b) – Saved values Indicates that the library should return the saved
values. The pages you request are returned, with each supported parameter
set to its saved value. Parameters not supported by the library are set to 0.
Note: For a PC value of 3, if no page has been saved, the library returns default
values.
