Hi,
I need some advice to interpretate the ISO 7816-3
normative: ISO 7816-3 states that the Work Waiting
Time for T=0 is calculated as follows:
wwt = 960 * D * WI * work etu.
I use this value as timeout for receiving chars from
the card.
I'm not sure how to calculate this value when etu =
1/9600 s (default value when there is no PTS):
a) work etu = (1/D) * (F/fs) where fs=3571200
So wwt is equals to:
wwt = 960 * WI * F / 3571200
For a cyberflex this gives 1376 ms and for cryptoflex
3200 ms.
b) Use the actual work etu (1/9600 seconds):
wwt = 960 * D * WI * (1/9600)
For cyberflex this gives 8000 ms and for cryptoflex
3200 ms.
Any advice is welcomed.
Thanks,
Carlos.
