These limits are compared Zone 1 and Zone 2 registers and trigger the optional
ALERT
signal pin and status bits that may
be enabled in Register 09h, Bit-5. The limits are in binary temperature format representing values from 0 to +127 degrees.

The Alert Status Register is a read-only register for reporting the state of the aSC7512’s alarms. It is a read-only register
located at 02h. When any high or low Zone 1 (remote) limits or high or low Zone 2 (local) limits are exceeded, bits 3 through
6 are set accordingly and the
ALERT
pin 6 will be driven low. If the remote sensor is open-circuit, bit 2 will be set and
the
ALERT
will be asserted. Reading the status register will re-set these flags if the alerted condition has been removed,
however, the
ALERT
pin will remain asserted until the master has serviced the SMBus alert. This register is read-only – a
write to this register has no effect.
