Table 17. Communication mode
1) Access via UART service and SPI possible. In case of hard or soft reset the register is reset to the hard reset value or soft reset
value respectively.
Table 18. E981.03 mode register values
Table 19. IC product ID (read only)
1) Access via UART service and SPI possible. In case of hard reset the register is reset to the hard reset value.
The state of several pins are accessible via register address PINS. The read value changes with pin voltages with-
out respect to IC state.
Table 20. Mode control and baud rate select pin values
1) Access via UART service and SPI possible.
ELMOS Semiconductor AG reserves the right to change the detail specifications as may be required to permit improvements in the design of its products.

Remarks
reset state is active if internal power supply is down
0x04 is the reset value of register CMODE
Normal Mode is active in case of CMODE values that
do not define an other communication mode.
