Status Registers Functions

Status registers 1, 2, and 3 (Tables 8, 9, 10) indicate

which (if any) temperature thresholds have been

exceeded and if there is an open-circuit or short-circuit

fault detected with the external sense junctions. Status

exceeded the threshold limit set in the ALERT registers

for the local or remote-sensing diodes. Status register 2

indicates if the measured temperature has exceeded

the threshold limit set in the OVERT registers. Status

short) in any of the remote-sensing channels.

Bits in the alert status register clear by a successful

read, but set again after the next conversion unless the

fault is corrected, either by a drop in the measured tem-

perature or an increase in the threshold temperature.

The ALERT interrupt output follows the status flag bit.

Once the ALERT output is asserted, it can be deassert-

ed by either reading status register 1 or by successfully

responding to an alert response address. In both cases,

the alert is cleared even if the fault condition exists, but

the ALERT output reasserts at the end of the next con-

version. Reading the status 2 register does not clear the

OVERT interrupt output. To eliminate the fault condition,

STOP

Standby Mode Control Bit. If STOP is set to logic 1, the MAX6698 stops

converting and enters standby mode.

POR

Reset Bit. Set to logic 1 to put the device into its power-on state. This bit is self-

clearing.

TIMEOUT

Timeout Enable Bit. Set to logic 0 to enable SMBus timeout.

Fast remote 1

Channel 1 Fast Conversion Bit. Set to logic 1 to enable fast conversion of

channel 1.

Resistance

cancellation

Resistance Cancellation Bit. When set to logic 1, the MAX6698 cancels series

resistance in the channel 1 thermal diode.
