CCID descriptor statistics: dwProtocols
Article from the serie "CCID descriptor statistics"
The dwProtocols field is a number value from the CCID USB descriptor:
RRRR –Upper Word- is RFU = 0000h
PPPP –Lower Word- Encodes the supported protocol types. A ‘1’ in a given bit position indicates support for the associated ISO protocol.
0001h = Protocol T=0
0002h = Protocol T=1
All other bits are reserved and must be set to zero. The field is intended to correspond to the PCSC specification definitions. See PCSC Part3. Table 3-1 Tag 0x0120.
Example: 00000003h indicates support for T = 0 and T = 1.
