DAS debug instrument (DI): gdi2das

Resource Name

AccessPort

DASserver

Description

The port used to connect to the wiggler.

The DAS Server used for communication.

DasTimeOut

The timeout value for communication with the DAS server in milliseconds. The default is 0x4000.

RegisterFile

15.4. Initialize Elements

The initialize

elements are used to initialize SFRs at startup. This is also done using a resource of the debug instrument. The following resource Ids exist for the DAS debug instrument (gdi2das):

Resource Name

einit init

Description

Initialize an SFR that is protected with the ENDINIT flag.

Initialize an SFR that is not protected with the ENDINIT flag.
