- description: |
- Describe the specific driving setup property.
- For I2C pins, the existing generic driving setup can only support
- 2/4/6/8/10/12/14/16mA driving. But in specific driving setup, they
- can support 0.125/0.25/0.5/1mA adjustment. If we enable specific
- driving setup, the existing generic setup will be disabled.
- The specific driving setup is controlled by E1E0EN.
- When E1=0/E0=0, the strength is 0.125mA.
- When E1=0/E0=1, the strength is 0.25mA.
- When E1=1/E0=0, the strength is 0.5mA.
- When E1=1/E0=1, the strength is 1mA.
- EN is used to enable or disable the specific driving setup.
- Valid arguments are described as below:
- 0: (E1, E0, EN) = (0, 0, 0)
- 1: (E1, E0, EN) = (0, 0, 1)
- 2: (E1, E0, EN) = (0, 1, 0)
- 3: (E1, E0, EN) = (0, 1, 1)
- 4: (E1, E0, EN) = (1, 0, 0)
- 5: (E1, E0, EN) = (1, 0, 1)
- 6: (E1, E0, EN) = (1, 1, 0)
- 7: (E1, E0, EN) = (1, 1, 1)
- So the valid arguments are from 0 to 7.

- 1: (R1, R0) = (0, 1) which means R1 disabled and R0 enabled.
- 2: (R1, R0) = (1, 0) which means R1 enabled and R0 disabled.
- 3: (R1, R0) = (1, 1) which means R1 enabled and R0 enabled.
