internal 120K pull up.
Serial data of I
resistor.
Serial clock of I
resistor.
Deciding the reference current for the differential pairs. The
pin was connected to the precision resistor tied to ground to
decide the appropriate current; 475 ohm is the standard value.
System reset signal when the watchdog is time out. This pin
will generate 250ms low phase when the watchdog timer is
timeout. This is internal 120K pull up.
Power good is a HIGH active input signal used to determine
when FS [4:0] are valid to be sample.
Power Down Function. This is power down pin, LOW active
(PD).
This is internal 120K pull up.
