C bus. This pin must be pulled-up using a pull-
up resistor of at least 1 k.
SDA 5 I/O Serial data input for the I
2
C bus. This pin must be pulled-up using a pull-up
resistor of at least 1 k.
VDD 1 P Core voltage supply pin.
VDDO 7 P Output voltage supply pin for CLK0, CLK1, and CLK2. See "6.2. Power
Supply Sequencing" on page 21.
GND 8 P Ground.
*Note: I = Input, O = Output, P = Power
