... bit is a logic ‘0’, the SMBus Host is writing data to the client device. If this bit is a logic ‘1’, the SMBus Host is reading data from the client device. The EMC1413-A and EMC1414-A SMBus slave address is determined by the pull-up resistor on the THERM pin as shown in The Address decode is performed by pulling known currents from VDD through the external resistor causing the pin voltage to drop based on the respective current / resistor relationship ...

Set the MASK bit to clear the ALERT pin. ...
Page 18
... The EMC1413 and EMC1414 have two levels of monitoring. The first provides a maskable ALERT signal to the host when the measured temperatures exceeds user programmable limits. This allows the EMC1413 and EMC1414 to be used as an independent thermal watchdog to warn the host of temperature hot spots without direct control by the host. The second level of monitoring provides a non maskable interrupt on the THERM pin if the measured temperatures meet or exceed a second programmable limit ...

... Programmable External Diode Ideality Factor The EMC1413/EMC1414 is designed for external diodes with an ideality factor of 1.008. Not all external diodes, processor or discrete, will have this exact value. This variation of the ideality factor introduces error in the temperature measurement which must be corrected for. This correction is typically done using programmable offset registers ...

... Diode Faults The EMC1413/EMC1414 detects an open on the DP and DN pins, and a short across the DP and DN pins. For each temperature measurement made, the device checks for a diode fault on the external diode channel(s). When a diode fault is detected, the ALERT pin asserts (unless masked, see Section 6 ...

... It will remain set until the temperature drops below the High Limit minus the THERM Hysteresis value. For example, if the CALRT[2:0] bits are set for 4 consecutive alerts on an EMC1413/EMC1414 device, the high limits are set at 70°C, and none of the channels are masked, then the ALERT pin will be asserted after the following four measurements: 1.
