Function
selects the register page
starts (and stops) the command execution
in- and output of 64 byte FIFO buffer
status flags of the receiver and transmitter and of the FIFO buffer
number of bytes buffered in the FIFO
diverse status flags
control bits to enable and disable passing of interrupt requests
interrupt request flags
selects the register page
diverse control flags e.g.: timer, power saving
error flags showing the error status of the last command executed
bit position of the first bit collision detected on the RF-interface
actual value of the timer
LSB of the CRC-Coprocessor register
MSB of the CRC-Coprocessor register
adjustments for bit oriented frames
selects the register page
controls the logical behaviour of the antenna driver pins TX1 and TX2
selects the conductance of the antenna driver pins TX1 and TX2
Defines the driver output conductance
sets the clock rate and the coding mode
selects the width of the modulation pulse
selects the width of the modulation pulse for SOF (I•CODE Fast-Mode)
Defines the framing for ISO14443-B communication
selects the register page
controls receiver behaviour
controls decoder behaviour
selects the bit-phase between transmitter and receiver clock
selects thresholds for the bit decoder
Control BPSK receiver behaviour
controls decoder behaviour and defines the input source for the receiver
controls clock generation for the 90° phase shifted Q-channel clock
