aSC7511
Status Register
The status register is a read-only register for reporting the
state of the aSC7511’s alarms. It is a read-only register
located at 02h.

BUSY
When any high or low local limits or high or low remote
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.
The local and remote
THERM
limit trip are reported in bits 0
and 1 respectively. These two bits are reset only by the
temperature falling below the
THERM
limit by the amount
set into the hysteresis register.
Table 3. Status Register Bit Assignments
Bit 7 will be high when the converter is busy. The list of
status register bit assignments is in Table 3. Each condition
is asserted when the bit is high. Default is 0.

Notes:
1. Low-byte values are fractional degrees, MSB of lower byte is 0.5°C
2. Changing to extended range adds 64°C to values reported, but limit settings are not changed and must be corrected by the user.
