SDI011 REFERENCE MANUAL 31
BAD_ATR_TS
BAD_ATR_TCK
ICC_MUTE
The following sub-sections discuss when and why these error codes are returned:
5.4.1.3.1. HW_ERROR
This error code is returned when a hardware short circuit condition is detected, during
application of power to the card or if any other internal hardware error is detected. This error
code has been defined in the error code table 6.2-2 of the CCID specification.
5.4.1.3.2. XFR_PARITY_ERROR
This error code is returned when a parity error condition is detected. This error will be reported
in the response to a PC_to_RDR_XfrBlock message. This error code has been defined in the
error code table 6.2-2 of the CCID specification.
5.4.1.3.3. ICC_MUTE
This error code is returned when the card does not respond until the reader time out occurs.
This error will be reported in the response to PC_to_RDR_XfrBlock message and
PC_to_RDR_IccPowerOn messages. This error code has been defined in the error code table
6.2-2 of the CCID specification.
5.4.2. Automatic PPS for the contactless interface
Automatic PPS is implemented in SDI011‘s driver. This means that by default SDI011 switches
to the maximum communication speed indicated by the card during its selection. Automatic
PPS can be disabled using escape messages as explained later in this manual.
When Auto PPS is disabled (discussed in escape messages section) the reader works at the
default baud rate of 106kbps. An escape command has been introduced in the driver to force
the required baud rate.
The maximum speed supported by SDI011 is 424Kbps by default. Using escape messages as
explained later in this manual it is possible to change this.
