// ----------------------------------------------------------------------
// NOTE: In some ROMs between 3.0 and 3.3 (inclusive), OEMs may have
// ROM tokens present in the ROM that were detected by the boot code
// in order to set the various HwrMiscFlags and GHwrMiscFlagsExt
// settings.  That scheme is no longer relevant, since starting with
// version 3.5 and later, it is now the responsibility of the HAL
// to set these flags, using whatever means necessary to determine
// what "features" the device has that the higher level OS may want
// to know about.
//
// These flags are defined in this public header file since both
// of these low memory globals are published as system features
// (sysFtrNumHwrMiscFlags and sysFtrNumHwrMiscFlagsExt) in <SystemMgr.h>.
// These features are for third party software that may (for whatever
// reason) want to know about certain hardware differences without
// having to read the low memory globals directly.
//
// Palm OS v3.1 was the first OS to publish sysFtrNumHwrMiscFlags as a feature.
//  Call FtrGet first; if the feature doesn't exist, check the OS version:
// Palm OS v2.0 and 3.0 have GHwrMiscFlags defined as a low memory global.
// Palm OS v1.0 did not have GHwrMiscFlags, so its contents are unpredictable.
//      Any devices running Palm OS v1.0 devices should assume zero for all flags.

  hwrMiscFlagHasSWContrast   = $0200; // set if UI should support software contrast
  hwrMiscFlagInvertLCDForBL  = $0400; // set if we need to invert LCD w/Backlight
  hwrMiscFlagHasMiscFlagExt  = $0800; // set if we have new hwrMiscFlagsExt

  // The following bit flags are set by HwrIdentifyFeatures.
  // They allow software to read the hardware ID without poking at hardware.
  // They also provide some isolation from different ID detection schemes
  // such as if the ID detection mechanism should change with EZ...

  hwrMiscFlagID1             = $1000; // set if ID bit keyBitHard1 was set
  hwrMiscFlagID2             = $2000; // set if ID bit keyBitHard2 was set
  hwrMiscFlagID3             = $4000; // set if ID bit keyBitHard3 was set
  hwrMiscFlagID4             = $8000; // set if ID bit keyBitHard4 was set
  hwrMiscFlagIDMask          = $F000;
  hwrMiscFlagIDOffset        = 12;     // Bits to shift to get a numeric ID

// NOTE: Currently, the '328 IDs don't overlap with the 'EZ IDs.  This is NOT a requirement,
// but is convenient for the time being as it makes it one step easier to identify a device.
// If the spaces are forced to overlap, it will be necessary to first check the processor
// type (328 or EZ) and then parse the product ID code.  Fortunately, this scheme is rapidly
// becoming obsolete since it was based on reading the keyboard I/O pins, and new products
// are starting to move their keyboard I/O bits to new places.  With the introduction of
// different HAL modules, identifying the actual hardware is now something the HAL code
// will do when the device boots.  The HAL need only do whatever it needs to do to uniquely
// tell the difference between those devices on which it is capable of operating.  Once
// the hardware is identified, the appropriate hwrMiscFlag and hwrMiscFlagExt bits can be
// set to tell the OS what features are present, and the appropriate hardware ID information
// can also be set so higher level software can uniquely identify the OEM/Device/HAL info.
//
// Changes
//  3/16/99 SCL: Documented '328 and 'EZ IDs and how the space could overlap if necessary
//  3/31/99 SRJ: hwrMiscFlagIDUndetermined created, used specifically during the boot sequence
//               before we have done HwrIdentifyFeatures().
// 10/29/99 SCL: Renamed hwrMiscFlagIDOther to hwrMiscFlagIDCheckROMToken
// 10/29/99 SCL: Assigned hwrMiscFlagIDUnused1 to hwrMiscFlagIDUndetermined for Palm OS 3.5
// 10/29/99 SCL: Assigned hwrMiscFlagIDUnused2 to hwrMiscFlagIDCheckOEMFtrs for Palm OS 3.5
// 11/ 2/99 SCL: Assigned hwrMiscFlagIDUnused3 to hwrMiscFlagIDCobra2 for Palm OS 3.5

// hwrMiscFlagIDCheckROMToken indicates that the actual device ID information
// should be read from hwrROMTokenHardwareID using SysGetROMToken or HwrGetROMToken.
// Attached to this token is the OEM ID and the OEM-specific Product ID.
// This scheme was used in Palm OS releases prior to 3.5.  See <HwrROMToken.h> for details.
// This ID is also reported when booting on PalmPilot devices (aka 2.0 hardware).

// or system globals (hwrOEMCompanyID, hwrOEMDeviceID, and hwrOEMHALID).
