Introduction
The AD/DA module uses a chip that is a 12-bit A/D and D/A converter
with configurable 8-channel interface, which can be configured as any
combination of ADC/DAC/GPIO and shares the I2C bus with the RTC
module. The input and output interface uses 8pin, and the connection
diagram is follows.
