ATR statistics: TB3 - Global after T=15 in TDi–1
Article from the series "ATR statistics".
TB3 - Global after T=15 in TDi–1
For T=1 protocol the first TBi encodes Block Waiting Integer and Character Waiting Integer. The high nibble encodes BWI. The low nibble encodes CWI.
For T=15 protocol TBi the coding is defined in the document ETSI TS 102 221 V10.0.0 (2011-12) chapter "6.3.3 Global Interface byte"

The list above is not really informative since both BWI and CWI are coded in the same byte.BWI
