initInstance(self)

source code

Parse ATR and initialize members:
TS: initial character
T0: format character
TA[n], TB[n], TC[n], TD[n], for n=0,1,...: protocol parameters
    note: protocol parameters indices start at 0, e.g.
    TA[0], TA[1] correspond to the ISO standard TA1, TA2
    parameters
historicalBytes: the ATR T1, T2, ..., TK historical bytes
TCK: checksum byte (only for protocols different from T=0)
FI: clock rate conversion factor
DI: voltage adjustment factor
PI1: programming voltage factor
II: maximum programming current factor
N: extra guard time

getChecksum(self)

source code

Return the checksum of the ATR. Checksum is mandatory only for T=1.
