EZ-USB Firmware Frameworks
5.3.2.2
DR_GetInterface()
BOOL DR_GetInterface()
This function is called before the frameworks implement the Get Interface device request. The regis-
ter array SETUPDAT contains the current eight byte setup command. If TRUE is returned, the frame-
works will implement the command. If FALSE is returned, it will do nothing.
5.3.2.3
DR_SetInterface()
BOOL DR_SetInterface()
This function is called before the frameworks implement the Set Interface device request. The regis-
ter array, SETUPDAT, contains the current eight-byte setup command. It is the responsibility of this
routine to save the new interface setting and to do any necessary device configuration. If TRUE is
returned, the frameworks will implement the command. If FALSE is returned, it will do nothing.
5.3.2.4
DR_GetConfiguration()
BOOL DR_GetConfiguration()
This function is called before the frameworks implement the Get Configuration device request. The
register array, SETUPDAT, contains the current eight-byte setup command. If TRUE is returned, the
frameworks will implement the command. If FALSE is returned, it will do nothing.
5.3.2.5
DR_SetConfiguration()
BOOL DR_SetConfiguration()
This function is called before the frameworks implement the Set Configuration device request. The
register array, SETUPDAT, contains the current eight byte setup command. By default, the frame-
works parses the descriptor table to determine the new configuration interface and its endpoints. It
then configures the EZ-USB control registers to reflect these new endpoints. If the configuration is
set to 0 then the frameworks will invalidate all of the endpoints. If TRUE is returned, the frameworks
will implement the command. If FALSE is returned, it will do nothing.
5.3.2.6
DR_GetStatus()
BOOL DR_GetStatus()
This function is called before the frameworks implement the Get Status device request. The register
array, SETUPDAT, contains the current eight-byte setup command. If TRUE is returned, the frame-
works will implement the command. If FALSE is returned, it will do nothing.
5.3.2.7
DR_ClearFeature()
BOOL DR_ClearFeature()
This function is called before the frameworks implement the Clear Feature device request. The reg-
ister array, SETUPDAT, contains the current eight-byte setup command. If TRUE is returned, the
frameworks will implement the command. If FALSE is returned, it will do nothing.
5.3.2.8
DR_SetFeature()
BOOL DR_SetFeature()
This function is called before the frameworks implement the Set Feature device request. The regis-
ter array, SETUPDAT, contains the current eight-byte setup command. If TRUE is returned, the
frameworks will implement the command. If FALSE is returned, it will do nothing.
