Register Structure
The supply voltage range is 4.4V to 5.25V.
Figure 10-6. Car Application
The microcontroller interface is a level converter which converts all internal digital signals which
are referred to the DVCC voltage, into the voltage used by the microcontroller. Therefore, the pin
VSINT can be connected to the supply voltage of the microcontroller in the case the microcon-
troller has another supply voltage than the ATA5823/ATA5824.
The configuration of the transceiver is stored in RAM cells. The RAM contains a 16
TX/RX data buffer and a 8
interface (CS, SCK, SDI_TMDI, SDO_TMDO).
The 1
The RAM and the status information is stored as long as the transceiver is in any active mode
(DVCC = VS1) and gets lost if the transceiver is in the OFF mode (DVCC = OFF).
After the transceiver is turned on via pin PWR_ON = High or pin N_PWR_ON = Low the control
registers are in the default state.
8-bit status register is not part of the RAM and is readable via the 4-wire serial interface.
