* <b>HID_STATETABLE_STACK_DEPTH</b> - ( \ref Group_HIDParser ) \n
* HID reports may contain PUSH and POP elements, to store and retrieve the current HID state table onto a stack. This
* allows for reports to save the state table before modifying it slightly for a data item, and then restore the previous
* state table in a compact manner. This token may be defined to a non-zero value to give the maximum depth of the state
* state table in a compact manner. This token may be defined to a non-zero 8-bit value to give the maximum depth of the state
* table stack. If not defined, this defaults to the value indicated in the HID.h file documentation.
*
* <b>HID_USAGE_STACK_DEPTH</b> - ( \ref Group_HIDParser ) \n
* HID reports generally contain many USAGE elements, which are assigned to INPUT, OUTPUT and FEATURE items in succession
* when multiple items are defined at once (via REPORT COUNT elements). This allows for several items to be defined with
* different usages in a compact manner. This token may be defined to a non-zero value to set the maximum depth of the
* different usages in a compact manner. This token may be defined to a non-zero 8-bit value to set the maximum depth of the
* usage stack, indicating the maximum number of USAGE items which can be stored temporarily until the next INPUT, OUTPUT
* and FEATURE item. If not defined, this defaults to the value indicated in the HID.h file documentation.
*
* <b>HID_MAX_COLLECTIONS</b> - ( \ref Group_HIDParser ) \n
* HID reports generally contain several COLLECTION elements, used to group related data items together. Collection information
* is stored separately in the processed usage structure (and referred to by the data elements in the structure) to save space.
* This token may be defined to a non-zero value to set the maximum number of COLLECTION items which can be processed by the

*
* <b>HID_MAX_REPORTITEMS</b> - ( \ref Group_HIDParser ) \n
* All HID reports contain one or more INPUT, OUTPUT and/or FEATURE items describing the data which can be sent to and from the HID
* device. Each item has associated usages, bit offsets in the item reports and other associated data indicating the manner in which
* the report data should be interpreted by the host. This token may be defined to a non-zero value to set the maximum number of
* the report data should be interpreted by the host. This token may be defined to a non-zero 8-bit value to set the maximum number of
* data elements which can be stored in the processed HID report structure, including INPUT, OUTPUT and (if enabled) FEATURE items.
* If a item has a multiple count (i.e. a REPORT COUNT of more than 1), each item in the report count is placed separately in the
* processed HID report table. If not defined, this defaults to the value indicated in the HID.h file documentation.
