Setting this bit to 1 enters the Soft PowerDown Mode. This means, internal
current consuming blocks are switched off, the oscillator keeps running.
Setting this bit to 1 enters the Soft PowerDown Mode. This means, internal
current consuming blocks are switched off including the oscillator.
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.
Setting this bit to 1 stops the timer immediately.
Reading this bit will always return 0.
Setting this bit to 1 starts the timer immediately.
Reading this bit will always return 0.
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.
