6.5.2.

Command Field Descriptions

CID:

The Card ID assigned by the ATTRIB command.

PARAM: The PARAM byte selects the type of read operation to be performed.

Table 23. PARAM byte options for the Read User Zone command for 88RF PICCs.

Command

PARAM

Read User Zone (Normal / Legacy)

$00

Read User Zone with Integrated MAC

$80

All Other Values Are Not Supported

ADDR:

The starting address of the data to read.

L:

The number of bytes to read minus 1. L cannot exceed the size of the user zone.

Reading more than 64 bytes in a single operation is not recommended. In a typical application environment, optimal

transaction time is achieved by reading no more than 32 data bytes in a single operation.

CRC:

Communication error detection bytes.

6.5.3. Response Field Descriptions

CID:

The PICC transmits its assigned card ID in the response.

ACK:

Acknowledge, the command executed correctly.

NACK:

Not Acknowledge, the command did not execute correctly.

DATA:

The data bytes read from user memory.

MAC:

The checksum bytes read from the cryptographic engine.

STATUS: PICC status code.

CRC:

Communication error detection bytes.
