7.1. Command to the ACR100F (CCID)
In the normal operation, the ACR100F acts as a slave device with regard to the communication
between a computer and the reader. The communication is carried out in the form of successive
command-response exchanges. The computer transmits a command to the reader and receives a
response from the reader after the command has been executed. A new command can be transmitted
to the ACR100F only after the response to the previous command has been received.
There are two cases where the reader transmits data without having received a command from the
computer, namely, the Reset Message of the reader and the Card Status Message.
7.1.1. CCID Command Pipe Bulk-OUT Messages
The ACR100F shall follow the CCID Bulk-OUT Messages as specified in CCID section 4. In addition,
this specification defines some extended commands for operating additional features. This section
lists the CCID Bulk-OUT Messages to be supported by ACR100F.
7.1.1.1. PC_to_RDR_IccPowerOn
