CRIT[1:0]
Input
CRITICAL Setpoint Bits (See CRITICAL Setpoint Decode Table)
SCL
Input. SMBus serial clock. Clocks data into and out of the
MC1066.
SDA
Bidirectional. Serial data is transferred on the SMBus in
both directions using this pin.
ADD1, ADD0
Inputs. Sets the 7–bit SMBus address. These pins are
“tri–state,” and the SMBus addresses are specified in the
Address Decode Table.
(
NOTE:
The tri–state scheme allows up to nine MC1066s
on a single bus. A match between the MC1066’s address and
the address specified in the serial bit stream must be made
to initiate communication. Many SMBus–compatible
devices with other addresses may share the same 2–wire bus.
These pins are only active at power–on reset, and will latch
into the appropriate states.
ALERT/COMP*
Output, Open Collector, Active Low. The ALERT output
corresponds to the general SMBALERT signal and indicates
an interrupt event. The MC1066 will respond to the standard
SMBus Alert Response Address when ALERT is asserted.
Normally, the ALERT output will be asserted and latched
when any of the following occurs:
