Digital temperature sensor with overtemperature alarms

7.3 Register overview

The SA56004X contains three types of SMBus addressable registers: read-only (R),

write-only (W), and read-write (R/W). Attempting to write to any R-only register or read

data from any W-only register produces an invalid result. Some of the R/W registers have

separate addresses for reading and writing operations.

The registers of the SA56004X serve four purposes:

• Control and configuration of the SA56004X

• Status reporting

• Temperature measurement storage

• ID and manufacturer test registers

Table 5 describes the names, addresses, Power-On Reset (POR), and functions of each

register. The data of the temperature-related registers is in two’s complement format in

which the MSB is the sign bit. The 8-bit data of other registers is in 8-bit straight format.
