I/O
Serial clock: Clock I/O pins.
D/A converter
DA0
Output Analog output: D/A converter analog output pins.
AVCC
Input
This is the power supply pin for the D/A converter. When
the D/A converter is not used, this pin should be connected
to the system power supply (VCC).
AVSS
Input
This is the ground pin for the D/A converter. This pin should
be connected to the system power supply (0 V).
Vref
Input
This is the reference voltage input pin for the D/A converter.
When the D/A converter is not used, this pin should be
connected to the system power supply (VCC).
