IsReaderResultCodeOk function

This function returns CR95HF_SUCCESS_CODE if the CR95HF command has succeeded.

Table 22 describes the CR95HF_IsReaderResultCodeOk function.

4.15

IsReaderErrorCode function

This function returns CR95HF_SUCCESS_CODE value if the CR95HF command has returned

an error code. Table 23 describes the CR95HF_IsReaderErrorCode function.

4.16

IsCommandExists function

This function returns CR95HF_SUCCESS_CODE if the CmdCode value exists. Table 24

describes the CR95HF_IsCommandExists function.

Table 22.
