StandBy

Setting this bit to 1 enters the Soft PowerDown Mode. This means, internal

current consuming blocks are switched off, the oscillator keeps running.

PowerDown

Setting this bit to 1 enters the Soft PowerDown Mode. This means, internal

current consuming blocks are switched off including the oscillator.

Crypto1On

This bit indicates that the Crypto1 unit is switched on and therefore all data

communication with the card is encrypted.

This bit can only be set to 1 by a successful execution of the Authent2 Command.

TStopNow

Setting this bit to 1 stops the timer immediately.

Reading this bit will always return 0.

TStartNow

Setting this bit to 1 starts the timer immediately.

Reading this bit will always return 0.

FlushFIFO

Setting this bit to 1clears the internal FIFO-buffer’s read- and write-pointer

(FIFOLength becomes 0) and the flag FIFOOvfl immediately.

Reading this bit will always return 0.
