Reporting slot error and slot status registers in bulk-in
messages for the contactless interface
Each bulk-in message contains the values of the Slot Error register (bError) and the Slot
Status register (bStatus).
Theses values are the same as defined in the “Reporting slot error and slot status registers
in bulk-in messages for the contact interface” paragraph.
Interrupt in messages for the contactless card interface
The Interrupt-In endpoint is used to notify the host of events that may occur asynchronously
and outside the context of a command-response exchange between host and CCID. If the
host has sent a Bulk-Out message and is waiting for a Bulk-In message in response, and
