+              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.
