. RESET/RESET goes active if the Watchdog Timer is enabled and SDA
remains either HIGH or LOW longer than the selectable Watchdog time out period.
RESET/RESET goes active on power up and remains active for 250ms after the
power supply stabilizes. RESET is an active high open drain output. An external pull
up resistor is required on the RESET/RESET pin.

Serial Data.
SDA is a bidirectional pin used to transfer data into and out of the
device. It has an open drain output and may be wire ORed with other open drain or
open collector outputs. This pin requires a pull up resistor and the input buffer is
always active (not gated).
Serial Clock.
The Serial Clock input controls the serial bus timing for data input and
output.
Write Protect.
