The SLM756 module supports multiple hardware I2C bus interfaces. The default I2C pin definition functions are as
follows:
Table 4.11: Default I2C Interface Pin Description
CAM_I2C_SDA 23
Camera dedicated I2C
CAM_I2C_SCL 24
SENSOR_I2C_SDA 59
General purpose I2C, default for sensor
SENSOR_I2C_SCL 58
TP_I2C_SDA 72
General purpose I2C, default for TP
TP_I2C_SCL 71
Note: 1 These 3 groups of I2C have been internally pulled up to VERG_L6_1P8 by default 2.2K, so they cannot be used
as normal GPIOs.
2 For other I2C signals, please refer to the table (3.3 Multiplexing Function). If necessary, add an external pull-up
resistor.
