The supply voltage range is 4.4V to 6.6V and VAUX is connected to an inductive supply.
Figure 5-6.
The microcontroller interface is a level converter which converts all internal digital signals that
are referred to the DVCC voltage into the voltage used by the microcontroller. Therefore, the pin
VSINT has to be connected to the supply voltage of the microcontroller.
This makes it possible to use the internal voltage regulator/switch at pin VSOUT as in
on page 7
to the supply voltage of the microcontroller as in
The configuration of the transceiver is stored in RAM cells. The RAM contains a 16
TX/RX data buffer and a 6
interface (CS, SCK, SDI_TMDI, SDO_TMDO).

The RAM and the status information are stored as long as the transceiver is in any active mode
(DVCC = VS1 or DVCC = V_REG2) and are lost when the transceiver switches to OFF mode
(DVCC =OFF).
8-bit status register is not part of the RAM and is readable via the 4-wire serial interface.
