Configuration, ALERT Mask, and
OVERT Mask Registers
The configuration register controls the standby-mode bit,
the power-on-reset bit, the SMBus timeout enable bit,
and the extended-range enable bit. The ALERT mask
register enables or disables the ALERT interrupt out-
put. The OVERT mask register enables or disables the
OVERT interrupt output.
Figure 2 shows the checkboxes for the configuration reg-
ister. Each checkbox corresponds to a bit in the register.
Tables 2, 3, and 4 describe the function for each check-
box in the Configuration tab's group boxes.
Read the register by pressing the Read button. Change
the register by selecting or deselecting the desired func-
tions and pressing the Write button.
Status Register Functions
The Alert High Status (0x44), OVERT Status (0x45),
Diode Fault Status (0x46), and Alert Low Status
(0x47) group boxes monitor the four status registers and
display the critical and fault conditions that occur. See
Tables 5–8 for a list of the status conditions.
Read the status of each register by pressing the Read
Status button within each group box.
The Alert High Status (0x44) group box indicates
whether a measured local or remote temperature has
exceeded the associated threshold limit set in an ALERT
High Limit register.
The OVERT Status (0x45) group box indicates whether
a measured temperature has exceeded the associated
threshold limit set in an OVERT High Limit register.
