ADT7410
WRITING DATA
It is possible to write either a single byte of data or two bytes to
the ADT7410, depending on which registers are to be written.
Writing a single byte of data requires the serial bus address, the
data register address written to the address pointer register,
followed by the data byte written to the selected data register.
This is shown in Figure 15.
For the T
it is possible to write to both the MSB and the LSB registers in

the same write transaction. Writing two bytes of data to these
registers requires the serial bus address, the data register address
of the MSB register written to the address pointer register,
followed by the two data bytes written to the selected data
register. This is shown in Figure 16.
If more than the required number of data bytes is written to a
register, the register ignores these extra data bytes. To write to
a different register, a start or repeated start is required.
