Bit 7 of the Consecutive ALERT register enables the SMBus timeout feature when set to 1 (the default
setting is 0). When enabled, the SMBus will timeout after approximately 25ms of inactivity.
describes how bits 3-1 of the Consecutive ALERT register set how many consecutive error conditions
must occur for each temperature measurement zone before the
These error conditions include diode faults and exceeding temperature limits. The default value is one
which means that any out-of-limit measurement or any diode fault will cause the
to be asserted. Any combination of bits 3-1 other than those shown will result in a value of one.
