Protocol Data Structure for Protocol T=1 (dwLength=00000007h)
Offset Field Size Value Description
10 bmFindexDindex 1
B7-4 – FI – Index into the table 7 in ISO/IEC
7816-3:1997 selecting a clock rate conversion
factor
B3-0 – DI - Index into the table 8 in
ISO/IEC 7816-3:1997 selecting a baud rate
conversion factor
11 BmTCCKST1 1
B7-2 – 000100b
B0 – Checksum type (b0=0 for LRC, b0=1 for
CRC)
B1 – Convention used (b1=0 for direct, b1=1
for inverse) Note: The CCID ignores this bit.
12 BGuardTimeT1 1
Extra Guardtime (0 to 254 etu between two
characters). If value is FFh, then guardtime is
reduced by 1 etu.

The response to this message is the RDR_to_PC_Parameters message.
7.1.2. CCID Bulk-IN Messages
The Bulk-IN messages are used in response to the Bulk-OUT messages. ACR101 (CCID) shall
follow the CCID Bulk-IN Messages as specified in section 4. This section lists the CCID Bulk-IN
Messages to be supported by ACR101 (CCID).
