2	80	TD1	Higher nibble 8 means: no TA2, TB2, TC2 only
			TD2 is following.
			Lower nibble 0 means T = 0

E.g 1. ATR for DESFire = { 3B 81 80 01 80 80 } // 6 bytes of ATR

ACR122L-USB-ACS

Hint: Use the APDU “FF CA 01 00 00” to distinguish the ISO14443A-4 and ISO14443B-4 PICCs, and retrieve the full ATS if available. ISO14443A-3 or ISO14443B-3/4 PICCs do have ATS returned.

APDU Command = FF CA 01 00 00

APDU Response = 06 75 77 81 02 80 90 00

ATS = {06 75 77 81 02 80}

E.g 2. ATR for ST19XRC8E = { 3B 8C 80 01 50 12 23 45 56 12 53 54 4E 33 81 C3 55} // 12 bytes of ATQB, No CRC-B

ATQB = {50 12 23 45 56 12 53 54 4E 33 81 C3}

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.

Example 1: To read the existing LED State.

//Assume both LED_0 and LED_1 are OFF initially //

//Not link to the buzzer //

APDU = “FF 00 40 00 04 00 00 00 00”

Response = “90 00”. LED_0 and LED_1 LEDs are OFF.

Example 2: To turn on LED_0 and LED_1

//Assume both LED_0 and LED_1 are OFF initially //

//Not link to the buzzer //

APDU = “FF 00 40 0F 04 00 00 00 00” Response = “90 03”. LED_0 and LED_1 are ON,

ACR122L-USB-ACS

#To turn off both LED_0 and LED_1, APDU = “FF 00 40 0C 04 00 00 00 00”

Example 3: To turn off the LED_1 only, and left the LED_0 unchanged.

//Assume both LED_0 and LED_1 are ON initially //

//Not link to the buzzer //

APDU = “FF 00 40 04 04 00 00 00 00”
