STTS751 register summary
STTS751
Doc ID 16483 Rev 4
4.1
STTS751 register formats and details
The STTS751 register set is comprised of the 16 addresses shown in Table 9. The
individual registers are accessed by transferring their addresses via the SMBus interface as
(Section 3.5) the address used is the address sent in the previous WRITE, READ or SEND
byte sequence.
An example read sequence of the Therm hysteresis register, address 21h, with its default
value, 0Ah, is shown below. The slave address used is 90h. The gray data is sent by the
STTS751 while the white data is sent by the host.
Note:
All eight bits are used to select the register.
4.2
Temperature register format
The temperature data is a 12-bit number and is stored in two's complement format spanning
the high byte and low byte registers as shown in Table 11.
The integer portion of the temperature is stored in the high byte, and the fractional portion in
the low byte. The lower four bits of the low byte will always read 0. At power-up, the
STTS751 defaults to 10-bit resolution. Thus, bits b5 and b4 of the lower byte will also read 0
until the device is configured to a higher resolution (via the Tres bits in the configuration
register).
