Register Descriptions

The SPA Registers view displays the contents of several important 32-bit registers on the selected SPA. All of the registers except the SPA Revision register are on the SAIL ASIC. The SPA Revision register is contained in flash SEEPROM on the SPA.

The contents of the following registers can be viewed. The complete register contents are shown in raw (32-bit hexadecimal) form; by clicking on the plus (+) sign to the left of the register name, key fields in the register are identified and their values are interpreted.

NOTE: For all multi-field registers (all but the SPA Revision register), the fields that are broken out separately for viewing are underscored in the tables that follow.


Viewing Register Contents

The viewable SPA registers appear in a single pane labeled For SPA N (where N = SPA number). Associated with the pane is a SPA choice box used to select the SPA containing the registers to be viewed.
 

Procedure

View the register contents for the selected SPA as follows:
  1. Select the SPA containing the registers you want to view with the SPA choice box.
  2. Click the plus (+) sign to the left of the desired SPA register to see the viewable fields for the register. For example, to see the fields for the Chip Identification (CIN) register, click on the plus (+) sign to the left of CIN.
  3. Expand all SPA registers (click on + signs) as needed.
With the fields for a SPA register displayed, they can be collapsed and hidden by clicking on the negative (-) sign to the left of the register.
