Remark:
1. The LED State operation will be performed after the LED Blinking operation is completed.
2. The LED will not be changed if the corresponding LED Mask is not enabled.
3. The LED will not be blinking if the corresponding LED Blinking Mask is not enabled. Also, the
number of repetition must be greater than zero.
4. T1 and T2 duration parameters are used for controlling the duty cycle of LED blinking and Buzzer
Turn-On duration.
For example, if T1=1 and T2=1, the duty cycle = 50%. #Duty Cycle = T1 / (T1 + T2).
5. To control the buzzer only, just set the P2 “LED State Control” to zero.
6. The make the buzzer operating, the “number of repetition” must greater than zero.
7. To control the LED only, just set the parameter “Link to Buzzer” to zero.

7.1. How to access PCSC Compliant Tags (ISO14443-4)?
Basically, all ISO 14443-4 complaint cards (PICCs) would understand the ISO 7816-4 APDUs. The
ACR122L-USB Reader just has to communicate with the ISO 14443-4 complaint cards through exchanging
ISO 7816-4 APDUs and Responses. ACR122L-USB will handle the ISO 14443 Parts 1-4 Protocols
internally.
MIFARE 1K, 4K, MINI and Ultralight tags are supported through the T=CL emulation. Just simply treat the
MIFARE tags as standard ISO14443-4 tags. For more information, please refer to topic “PICC Commands
for MIFARE Classic Memory Tags”

In which,
The ATQB = 50 57 26 34 D9 1C 2D 94 11 F7 71 85. It is an ISO14443-4 Type B tag.

7.2. How to access DESFIRE Tags (ISO14443-4)?
The DESFIRE supports ISO7816-4 APDU Wrapping and Native modes. Once the DESFire Tag is
activated, the first APDU sent to the DESFire Tag will determine the “Command Mode”. If the first
APDU is “Native Mode”, the rest of the APDUs must be in “Native Mode” format. Similarly, If the first
APDU is “ISO7816-4 APDU Wrapping Mode”, the rest of the APDUs must be in “ISO7816-4 APDU
Wrapping Mode” format.
Example 1: DESFIRE ISO7816-4 APDU Wrapping.
// To read 8 bytes random number from an ISO 14443-4 Type A PICC (DESFIRE)
APDU = {90 0A 00 00 01 00 00}
Class = 0x90; INS = 0x0A (DESFire Instruction); P1 = 0x00; P2 = 0x00
Lc = 0x01; Data In = 0x00; Le = 0x00 (Le = 0x00 for maximum length)
Answer: F2 84 A2 42 E1 3B C4 66 91 AF[$91AF]
# Status Code{91 AF} is defined in DESFIRE specification. Please refer to the DESFIRE specification
for more details.

Step 2: Send an APDU {90 AF 00 00 00} to get the second frame. INS=0xAF
Answer: 04 01 01 01 00 1A 05 91 AF[$91AF]
Step 3: Send an APDU {90 AF 00 00 00} to get the last frame. INS=0xAF

Example 3: DESFIRE Native Command.
// We can send Native DESFire Commands to the reader without ISO7816 wrapping if we find that the
Native DESFire Commands are more easier to handle.
// To read 8 bytes random number from an ISO 14443-4 Type A PICC (DESFIRE)
APDU = {0A 00}
Answer: AF 53 44 D1 69 4C 20 B6 2B[$B62B]
In which, the first byte “AF” is the status code returned by the DESFire Card.
The Data inside the blanket [$B62B] can simply be ignored by the application.

Hints:
In DESFIRE Native Mode, the status code [90 00] will not be added to the response if the response
length is greater than 1. If the response length is less than 2, the status code [90 00] will be added in
order to meet the requirement of PCSC. The minimum response length is 2.
