Product data sheet
13.3.1 Write access
A more detailed description of all registers, that can be accessed by the customer, is given
in
the address and write or read request respectively, is listed there.
In order to write data into the EEPROM, the internal charge pump must be enabled at first
by setting the bits EEP_CP_CLOCK_EN and EEP_WRITE_EN and waiting for t
Afterwards the following procedure must be done:

data on the bus, which is either caused by the master or by the slave. The signals master
output enable and slave output enable just symbolize if the master or the slave output is
enabled or disabled respectively.
Note: As already mentioned in
using the write procedure. Without entering the command mode a digital communication
is not possible and the sensor would work in normal operation mode. After changing a
single address the time t
checksum has to be recalculated and written, after changing the EEPROM constants

(1) Missing rising edges generate a time-out condition and the written data is ignored.
(2) If the master might not drive the bus, the bus is defined by the bus-pull.
