There is only one slave in the current design, it is recommended to
select only one pin for SCL. When multi pins are selected, the priority of
these bits is MO_I2C_EN > SCL_PIN76_EN > SCL_PIN67_EN.
0: Disable SDA from pin 76.
1: Enable SDA from pin 76.
There is only one slave in the current design, it is recommended to
