The host uses this command to control the 4 LEDs of the device when the device is not in non-User Control LED states. If the host sets an LED timer, the device reports completion via Notification User Interface Operation Complete - 0x1805 after the LED operation finishes.
Non-User Control LED state is when the device is in tamper, or currently running transaction with these commands:
Start Transaction - Command 0x1001
Card Emulation - Command 0x1840
Request PIN with Host Supplied Account Data - Command 0x2001
Request PIN with Card Supplied Account Data - Command 0x2002
When the device is in non-User Control LED states, it will return error if the host sends this command.
When the device is in the User Control LED state, and if there is any transaction that uses LEDs for the transaction status, the device will stop the User Control LEDs for that transaction to take over, and resume to the current system’s LED status after finishing that transaction.
The host is responsible for stopping the User Control LEDs so the device can get back to the system’s LEDs status if the device is in the User Control LEDs.
