3.4.3 I2C Module

There are two switches between at24c08 and EEPROM, when using i2c to visit EEPROM, it

will switch off and when using i2c to visit other external chip, it will switch on.

Following

settings is recommended:

EEPROM

SW1: on.
SW2: on

External chip

SW1: off.
SW2: off

Table 3.4.3 - 1 I2C Switch

3.4.4 A/D Module

Key module and temperature module use the ADC to detect the real-time operation and

environment temperature.
For key module please refer to the following figure 3.4.4 - 1
