SA56004X
Digital temperature sensor with overtemperature alarms
7.4 Power-on reset
When power is applied to the SA56004X, the device will enter into its Power-On Reset
(POR) state and its registers are reset to their default values. The configuration, status,
and temperature-reading registers remain in these states until after the first conversion.
As shown in
Table 4
this results in:
1. Command register set to 00h.
2. Local Temperature register (LTHB and LTLB) set to 0
°
C.
3. Remote Diode Temperature register (RTHB and RTLB) set to 0
°
C until the end of the
first conversion.
4. Status register (SR) set to 00h.
5. Configuration register (CON) set to 00h; interrupt latches are cleared, the ALERT and
T_CRIT output drivers are off and the ALERT and T_CRIT pins are pulled HIGH by
the external pull-up resistors.
6. Local T_CRIT temperature setpoints (LCS) and Remote T_CRIT temperature
setpoints (RCS) at 85
°
C.
7. Local HIGH setpoint (LHS) and remote HIGH temperature setpoint (RHSHB) at 70
°
C.
