Parameters definition
ENum:
0x00 ~ 0x0f – ENum represents the length of EPC number. The unit of ENum is word, and the
length of EPC should be less than 15 words. In this situation, parameters MaskMen,
MaskAdr, MaskLen, MaskData should all be left empty.
0xff – MaskMem, MaskAdr, MaskLen, MaskData should be provided instead of EPC parameters.
Reader will return a parameter error status in the response frame if other value is delivered in this
field.
EPC: EPC number of the target tag. Length of the EPC depends on the provided EPC number. The
unit of EPC number is word. During communication, the most-significant word and the
most-significant byte in a word will be transmitted first. It is essential to provide FULL EPC in this
command.
SPICmdSize: 1 byte, the byte length of SPI command. The valid range of SPICmdSize is 1 ~ 8.
All other values are reserved, reader will return a parameter error status in the response frame if
other value is delivered in this field.
SPIResSize: 1 byte, the byte length of response from SPI slave device. The valid range of
SPIResSize is 0 ~ 7. SPIResSize = 0 represents no response will be produced.
All other values are reserved, reader will return a parameter error status in the response frame if
other value is delivered in this field.
SPISclk: 1 byte, clock of the SPI bus.
0 – 40KHz;
1 – 80KHz;
2 – 160KHz;
3 – 320KHz.
All other values are reserved, reader will return a parameter error status in the response frame if
other value is delivered in this field.
SPIInitDelay: 1 byte, delay for SPI clock initialisation.
0 – 1 SCLK;
1 – 50us;
2 – 500us;
3 – 5ms.
All other values are reserved, reader will return a parameter error status in the response frame if
other value is delivered in this field.
