/* @file plustek-pp_p48xx.c
* @brief here we have all functionality according to the ASIC96001/3 based
* models.
*
* based on sources acquired from Plustek Inc.
* Copyright (C) 1998 Plustek Inc.
* Copyright (C) 2000-2004 Gerhard Jaeger <gerhard@gjaeger.de>
* also based on the work done by Rick Bronson
*
* History:
* - 0.30 - initial version
* - 0.31 - fixed a bug for the return value in p48xxDoTest
* - added additional debug messages
* - added function p48xxCheck4800Memory
* - 0.32 - added debug messages
* - fixed a bug in p48xxDoTest
* - disabled RD_WatchDogControl, lamp will be controlled by driver
* - 0.33 - added function p48xxSetAsicRegisters()
* - fixed a bug in p48xxDoTest (reset the ASIC registers)
* - removed p48xxPositionLamp
* - 0.34 - added some comments
* - 0.35 - added some comments
* - 0.36 - added function p48xxInitAllModules() to allow reinit of the modules
* - switching from Full- to Halfstep at ps->PhysicalDpi now in
* - p48xxSetGeneralRegister
* - fixed the color-inverse problem for model OP4800
* - 0.37 - move p48xxOpenScanPath, p48xxCloseScanPath
* and p48xxRegisterToScanner to io.c
* - removed // comments
* - added override for A3I scanner
* - 0.38 - added function p48xxPutToIdleMode()
* - added function p48xxCalibration
* - 0.39 - added A3I stuff
* - 0.40 - disabled A3I stuff
* - 0.41 - no changes
* - 0.42 - changed include names
* - 0.43 - no changes
