0x00 – Sleep Mode (resume from last instruction)
0x01 – Stop Mode (POR required)
MSR / NFC Option

0x00 – OFF
0x01 – ON (Swipe/Tap will wake from low power)
Use 00 01 to put the reader in Sleep Mode. It will awaken upon card presentation.
With 00 00, the reader will wake up with card

presentation. (The card-seated switch is always enabled; it cannot be disabled.)
Wakeup from Stop Mode involves a reboot (which takes several seconds). Wakeup from Sleep
Mode does not reboot.n
