1980 * The Central Management Sequencer (CSEQ) Scratch Memory is a 1024
1981 * byte memory. It is dword accessible and has byte parity
1982 * protection. The CSEQ accesses it in 32 byte windows, either as mode
1983 * dependent or mode independent memory. Each mode has 96 bytes,
1984 * (three 32 byte pages 0-2, not contiguous), leaving 128 bytes of
1985 * Mode Independent memory (four 32 byte pages 3-7). Note that mode
1986 * dependent scratch memory, Mode 8, page 0-3 overlaps mode
1987 * independent scratch memory, pages 0-3.
1988 * - 896 bytes of mode dependent scratch, 96 bytes per Modes 0-7, and
1989 * 128 bytes in mode 8,
1990 * - 259 bytes of mode independent scratch, common to modes 0-15.
1991 *
1992 * Sequencer scratch RAM is 1024 bytes. This scratch memory is
1993 * divided into mode dependent and mode independent scratch with this
1994 * memory further subdivided into pages of size 32 bytes. There are 5
1995 * pages (160 bytes) of mode independent scratch and 3 pages of
1996 * dependent scratch memory for modes 0-7 (768 bytes). Mode 8 pages
1997 * 0-2 dependent scratch overlap with pages 0-2 of mode independent
1998 * scratch memory.
1999 *
2000 * The host accesses this scratch in a different manner from the
2001 * central sequencer. The sequencer has to use CSEQ registers CSCRPAGE
2002 * and CMnSCRPAGE to access the scratch memory. A flat mapping of the
2003 * scratch memory is avaliable for software convenience and to prevent
2004 * corruption while the sequencer is running. This memory is mapped
2005 * onto addresses 800h - BFFh, total of 400h bytes.
2006 *
2007 * These addresses are mapped as follows:
