SCL010/01X REFERENCE MANUAL 26
5.4. Firmware
5.4.1. CCID-like transport protocol
SCL010/01X implements a transport protocol that is compliant with USB Device Class: Smart
Card CCID Specification for Integrated Circuit(s) Cards Interface Devices Revision 1.10.
This paragraph describes the CCID specification features that are implemented and those that are
not implemented.
 PC/SC 2.0 Compliant
 Firmware supports one contactless slot
 Firmware supports both T = 0 and T = 1 protocols for PICC
 The default PICC I/O data rate is 106kbps and the maximum supported data rate is
848kbps
5.4.1.1. CCID class requests supported
 Abort
 Get Clock Frequencies
 Get Data rates
5.4.1.2. CCID messages supported
The following CCID messages are supported when received through bulk-out endpoint.
 PC_to_RDR_IccPowerOn
 PC_to_RDR_IccPowerOff
 PC_to_RDR_GetSlotStatus
 PC_to_RDR_XfrBlock
 PC_to_RDR_Escape
 PC_to_RDR_Abort
The following CCID messages are NOT implemented and hence fail with command not supported
error:
 PC_to_RDR_ResetParameters
 PC_to_RDR_IccClock
 PC_to_RDR_T0APDU
 PC_to_RDR_Secure
 PC_to_RDR_Mechanical
 PC_to_RDR_SetDataRateAndClockFrequency
 PC_to_RDR_GetParameters
 PC_to_RDR_SetParameters
