LM75A
Digital temperature sensor and thermal watchdog
read a register that is different from the one that has been recently read, the pointer byte
must be included. However, a write to the LM75A must always include the pointer byte in
the statement. The bus communication protocols are described in
Section 7.10
.
At power-up, the Pointer value is equal to 0 and the Temp register is selected; users can
then read the Temp data without specifying the pointer byte.
7.4.2
Configuration register
The Configuration register (Conf) is a write/read register and contains an 8-bit
non-complement data byte that is used to configure the device for different operation
conditions.
Table 8
shows the bit assignments of this register.
7.4.3
Temperature register
The Temperature register (Temp) holds the digital result of temperature measurement or
monitor at the end of each analog-to-digital conversion. This register is read-only and
contains two 8-bit data bytes consisting of one Most Significant Byte (MSByte) and one
Least Significant Byte (LSByte). However, only 11 bits of those two bytes are used to store
the Temp data in 2’s complement format with the resolution of 0.125
°
C.
Table 9
shows the
bit arrangement of the Temp data in the data bytes.
