With SELSSI = 1 the communication timing is switched
to SSI compatibility. Data output is in binary format
starting with the MSB. It can be configured if the error
bits are to be send afterwards.

EEPROM INTERFACE
Serial EEPROM components permitting operation dresses 0-111 are mapped onto the BiSS addresses
from 3.3 V to 5 V can be connected (such as 24C02, for 16-127. If no EEPROM is connected the device must
example). When the device is switched on the memory be configured via BiSS and address 0 written last. In
area of bytes 0 to 15 is mapped onto iC-NQ’s registers. this case iC-NQ does not respond to addresses 16-
The higher memory areas, bytes 16-111, are readily 119; reading addresses 120-127 sends the device ID
available to the system via BiSS. The EEPROM ad- plus the contents of register 0 to address 124.
