SA56004X
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 twos complement format in
which the MSB is the sign bit. The 8-bit data of other registers is in 8-bit straight format.
