ATR statistics: TC4

Article from the series "ATR statistics".

TC4

TC4 should have the same meaning as TC3.

For T = 1: type of error detection code used

Bit 1 of the first TC for T=1 indicates the error detection code to be used:
  • CRC if bit 1 is set to 1;
  • LRC (default value) if bit 1 is set to 0.
Bits 8 to 2 of the first TC for T=1 are reserved for future use and shall be set to 0.

2072100.00 %

In my list of ATR none of them defines an TC4.
