ADT7408
Preliminary Technical Data
Rev. PrC | Page 16 of 22
SMBus/I2C Communications
The data registers in the ADT7408 are selected by the Pointer Register. At power-up the Pointer Register is set to 0x00, the location for
the Capability Register. The Pointer Register latches the last location it was set to. Each data register falls into one of the three types of
user accessibility:
1.
Read only
2.
Write only
3.
Write/Read same address
A Write to the ADT7408 will always include the address byte and the pointer byte. A write to any register, other than the pointer register,
requires two data bytes.
Reading data from the ADT7408 can take place either of two ways:
If the location latched in the Pointer Register is correct, then the read can simply consist of an address byte, followed by retrieving the two
data bytes.
If the Pointer Register needs to be set, then an address byte, pointer byte, repeat start, and another address byte will accomplish a read.
The data byte has the most significant bit first. At the end of a read, the ADT7408 can accept either Acknowledge (Ack) or No
Acknowledge (No Ack) from the Master (No Acknowledge is typically used as a signal for the slave that the Master has read its last byte).
It takes the ADT7408 97ms to measure the temperature.
Writing Data to a Register
Except the Pointer Register, all other Registers are 16-bits wide so two bytes of data are written to these register. Writing two bytes of data to these Register consists of
the serial bus address, the Data Register address written to the Pointer Register, followed by the two data bytes written to the selected Data Register. This is illustrated
in
Figure . If more than the required number of data bytes is written to a register then the register will ignore these extra data bytes. To write
to a different register, another START or repeated START is required.
