Serial Clock: SMBus clock signal. Operates up
to 400 kHz. Low-pass filtered.
Digital output which goes active whenever the
measured temperature exceeds a
programmable temperature limit.
Serial Data: SMBus bi-directional data signal
used to transfer serial data synchronous to the
SMBCLK. Low-pass filtered.
