4.2 Special Constructions
4.2.1 Values, Types, and Unit Exponents
The HID Report Descriptors in this section use the following definitions for values, units and unit
exponents.
The value communicated as part of a Report Descriptor is in terms of the Report Size and Report Count
attributes, combined with the Logical Minimum, Logical Maximum, and Units for data values associated
with that Report Item.
The value is treated in one of three ways:
As a bitfield
As a signed or unsigned integer value
As a float value
Bitfield
A value is identified as a bitfield when the Report Size field = 1. In this section, this is expressed
as HID_REPORT_SIZE(1). In this case, Logical Maximum, Logical Minimum, Units and Units
Exponent are not used.
Unsigned Integer
