Split contactless tag response functions

An contactless tag response can contain various information. The functions described

herein split the contactless tag response and return the offset byte into the pResponse

parameter.

3.9.1

ISO15693_SplitInventoryResponse function

This function returns the response flags, DSFID byte and UID extracted from the inventory

response.

Table 71.
