The command is allowed with the in TPDU mode. In APDU mode, the command is rejected.
Offset Field Size Value Description
0 bMessageType 1 61h PC_to_RDR_SetParameters
1 bwLength 4 Size of the
abProtocolDataStructure field
5 bSlot 1 00h Slot 0
6 bSeq 1 00-FFh Sequence number for the
command
7 bProtocolNum 1 01h Specifies what protocol data
structure follows.
00h = structure for protocol T=0
01h structure for protocol T=1
8 abRFU 2 Reserved for future use
10 abProtocolDataStructure Byte

Protocol Data Structure
Protocol data structure for protocol T=0 (bProtocolNum = 0) (dwLength = 00000005h):
Offset Field Size Value Description
10 bmFindexDindex 1 b7-4 – FI selecting a clock rate
conversion factor
b3-0 – DI selecting a baud rate
conversion factor
see table Fi/Di of ISO 7816-3
11 bmTCCKST0 1 00h, 02h For T=0,
b0 – 0b
b7-2 – 000000b
b1 = 0 direct convention
b1 = 1 inverse convention
CCID ignores bit b1
12 bGuardTimeT0 1 00h-FFh Extra Guard Time between two
characters. Add 0 to 254 etu to the
normal guard time 12 etu. FFh is
the same as 00h
13 bWaitingIntegerT0 1 00h-FFh WI for T=0 used to define WWT
14 bCLockStop 1 00h ICC clock stop support
00h = Stopping the clock is not
allowed
bCLockStop: Stopping the clock is not allowed for this parameter.
Protocol data structure for protocol T=1 (bProtocolNum = 1) (dwLength = 00000007h):
Offset Field Size Value Description
10 bmFindexDindex 1 b7-4 – FI selecting a clock rate
conversion factor
b3-0 – DI selecting a baud rate
conversion factor
see table Fi/Di of ISO 7816-3
11 bmTCCKST1 1 10h, 11h,
12h, 13h
For T=1,
b7-2 = 000100b
b0 = 0b – Checksum LRC
b0 = 1b – Checksum CRC
b1 = 0 - direct convention
b1 = 1 - inverse convention
CCID ignores bit b1
12 bGuardTimeT1 1 00-FFh Extra Guard Time between two
