Ground.
Serial Data Input/Output. SDA is the input/output pin for the 2-wire serial interface. The
SDA pin is open-drain output and requires an external pull-up resistor.
Serial Clock Input. SCL is used to synchronize data movement on the I
Frequency Test / Output Driver. Open drain. 512Hz output when Frequency Test is selected.
Output DC level by register selection. Frequency Test is prior.
