SA56004X
Digital temperature sensor with overtemperature alarms
7.8 SA56004X SMBus registers
7.8.1 Command register
The command register selects which register will be read or written to. Data for this
register should be transmitted during the Command Byte of the SMBus write
communication.
7.8.2 Local and remote temperature registers (LTHB, LTLB, RTHB, RTLB)
7.8.3 Configuration register (CON)
The configuration register is an 8-bit register with read address 03h and write address
09h. Table 8
shows how the bits in this register are used.

Description
POR state
7
ALERT
mask.
The ALERT interrupt is enabled when this bit is LOW. The ALERT interrupt
is disabled (masked) when this bit is HIGH.
0
6
RUN
/STOP.
Standby or run mode control. Running mode is enabled when this bit is
LOW. The SA56004X is in standby mode when this bit is HIGH.

4
Remote T_CRIT
mask.
The T_CRIT
output will be activated by a remote temperature that exceeds
the remote T_CRIT setpoint when this bit is LOW. The T_CRIT
output
will not be activated under this condition when this bit is HIGH.
