Temperature Limit Registers

The device contains both high and low limits for the temperature channels. If the measured

temperature meets or exceeds the high limit, the corresponding status bit is set, and the ALERT pin

is asserted. Likewise, if the measured temperature is less than or equal to the low limit, the

corresponding status bit is set and the ALERT pin is asserted.

The limit registers with multiple addresses are fully accessible at either address.

When the device is Standby or Current Sense only mode, updating the limit registers will have no effect

until the next conversion cycle occurs. This conversion cycle can be initiated via a write to the One-

Shot Register or by clearing the TMEAS_STOP bit in the Configuration Register (see Section 5.5).

5.8

One-Shot Register

Writing to the One-Shot register will automatically update those channels that are not currently

measured. If the device is Fully Active, writing to this register will have no effect. If the IMEAS_STOP

bit is set, writing to this register will update the VSENSE and VSOURCE voltage measurements. If the

TMEAS_STOP bit is set, writing to this register will update all of the temperature channel

measurements.
