Example 6: To make the Red and Green LEDs blink at 1 Hz three times.
// Assume both the Red and Green LEDs are initially OFF. //
// Both Initial Red and Green Blinking States are ON //
// The buzzer will turn on during both the T1 and T2 duration//
1 Hz = 1000 ms Time Interval = 500 ms ON + 500 ms OFF
T1 Duration = 500 ms = 0x05h
T2 Duration = 500 ms = 0x05h
Number of repetition = 0x03h
Link to Buzzer = 0x03h
APDU = “FF 00 40 F0 04 05 05 03 03h”
Response = “90 00h”
T1 =
500 ms
T2 =
500 ms
