   NAME
        ObtainBattSemaphore -- Obtain access to nonvolatile ram. (V36)

   SYNOPSIS
        ObtainBattSemaphore( )

        void ObtainBattSemaphore( void );

   FUNCTION
        Aquires exclusive access to the system nonvolatile ram.

   NAME
        ReadBattMem -- Read a bitstring from nonvolatile ram.  (V36)

   SYNOPSIS
        Error = ReadBattMem( Buffer, Offset, Len )
        D0                   A0      D0      D1

        ULONG ReadBattMem( APTR, ULONG, ULONG );

   FUNCTION
        Read a bitstring from nonvolatile ram.

   INPUTS
        Buffer          Where to put the bitstring.
        Offset          Bit offset of first bit to read.
        Len             Length of bitstring to read.

   RESULTS
        Error           Zero if no error.

   NOTES
        The battery-backed memory is checksummed. If a checksum error
        is detected, all bits in the battery-backed memory are
        silently set to zero.

        Bits in the battery-backed memory that do not exist are read
        as zero.

        Partial byte reads (less than 8 bits) result in the bits read
        being put in the low-order bits of the destination byte.

   NAME
        ReleaseBattSemaphore -- Allow nonvolatile ram to others.  (V36)

   SYNOPSIS

        void ReleaseBattSemaphore( void );

   FUNCTION
        Relinquish exclusive access to the system nonvolatile ram.

battmem.resource/WriteBattMem                   battmem.resource/WriteBattMem

   NAME
        WriteBattMem -- Write a bitstring to nonvolatile ram.  (V36)

   SYNOPSIS
        Error = WriteBattMem( Buffer, Offset, Len )
        D0                    A0      D0      D1

        ULONG WriteBattMem( APTR, ULONG, ULONG );

   FUNCTION
        Write a bitstring to the nonvolatile ram.

   INPUTS
        Buffer          Where to get the bitstring.
        Offset          Bit offset of first bit to write.
        Len             Length of bitstring to write.

   RESULTS
        Error           Zero if no error.

   NOTES
        The battery-backed memory is checksummed. If a checksum error
        is detected, all bits in the battery-backed memory are
        silently set to zero.

        Partial byte writes (less than 8 bits) result in the bits
        written being read from the low-order bits of the source byte.
