RESET/
RESET
Reset Output. RESET/RESET is an active LOW/HIGH, open
drain output which goes active whenever VCC falls below the
minimum VCC sense level. It will remain active until VCC rises
above the minimum VCC sense level for 250ms. 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. A falling edge of SDA, while SCL
also toggles from HIGH to LOW followed by a stop condition
resets the watchdog timer. RESET/RESET goes active on
power up and remains active for 250ms after the power supply
stabilizes.

SDA
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).
Watchdog Input. A HIGH to LOW transition on the SDA while
SCL also toggles from HIGH to LOW follow by a stop condition
resets the watchdog timer. The absence of this procedure with-
in the watchdog time out period results in RESET/RESET going
active.

SCL
Serial Clock. The serial clock controls the serial bus timing for
data input and output.
