Description
If set to logic 1, a not valid received data stream (less than 4 bits
received) will be ignored. The receiver will remain active.
Set to logic 0, the receiver is deactivated after receiving a data frame.
Set to logic 1, it is possible to receive more than one data frame. This bit
is only valid for data rates above 106 kbit/s to handle the Polling
command. Having set this bit, the receive and transceive commands will
not terminate automatically. In this case the multiple receiving can only
be deactivated by writing any command (except the Receive command)
to the CommandReg register or by clearing the bit by the host.
If set to logic 1, at the end of a received data stream an error byte is
added to the FIFO. The error byte is a copy of the ErrorReg register.
Reserved for future use.

Description
Set to logic 1, the output signal at pin TX2 will be inverted, if driver TX2
is enabled.
Set to logic 1, the output signal at pin TX1 will be inverted, if driver TX1
is enabled.
Set to logic 1, the output signal at pin TX2 will be inverted, if driver TX2
is disabled.
Set to logic 1, the output signal at pin TX1 will be inverted, if driver TX1
is disabled.
Set to logic 1, the output signal on pin TX2 will deliver continuously the
un-modulated 13.56 MHz energy carrier.
Set to logic 0, Tx2CW is enabled to modulate the 13.56 MHz energy
carrier.
Reserved for future use.
Set to logic 1, the output signal on pin TX2 will deliver the 13.56 MHz
energy carrier modulated by the transmission data.
Set to logic 1, the output signal on pin TX1 will deliver the 13.56 MHz
energy carrier modulated by the transmission data.
