conversion factor
11 bmTCCKST0 1 00h, 02h For T=0,
b0 – 0b
b7-2 – 000000b
b1 = 0 direct 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- 03h ICC clock stop support
00h = Stopping the clock is not
allowed

For T=0,
b7-2 = 000100b
b0 = 0b – Checksum LRC
b0 = 1b – Checksum CRC
b1 = 0 - direct convention
CCID ignores bit b1
12 bGuardTimeT1 1 00-FFh Extra Guard Time between two
characters. If value FFh, then
guard time is reduced by 1 etu.
13 bWaitingIntegersT1 1 00-9Fh b7-b4 = BWI value 0-9 valid
b3-b0 = CWI value 0-F valid
14 bCLockStop 1 00h- 03h ICC clock stop support
00h = Stopping the clock is not
allowed
15 bIfsc 1 01-FEh Size of negotiated IFSC
16 bNadValue 1 Value = 00h if CCID doesn’t
support a value other than the
default value.
Else the value respects ISO/IEC
7816-3 9.4.2.1
