Description
Set to logic 1, the timer starts automatically at the end of the transmission
in all communication modes at all speeds or when bit InitialRFOn is set to
logic 1 and the RF field is switched on.
In mode MIFARE and ISO14443-B 106kbit/s the timer stops after the 5th
bit (1 startbit, 4 databits) if the bit RxMultiple in the register RxModeReg is
not set. In all other modes, the timer stops after the 4th bit if the bit
RxMultiple the register RxModeReg is not set.
If RxMultiple is set to logic 1, the timer never stops. In this case the timer
can be stopped by setting the bit TStopNow in register ControlReg to 1.
Set to logic 0 indicates, that the timer is not influenced by the protocol.

Description
Reserved for future use.
The value of this register defines the conductance of the output
P-driver for the time of modulation. This may be used to regulate the
modulation index.
Note: The conductance value is binary weighted.
Note: During soft Power-down mode the highest bit is forced to 1.
