Number $113B
Short desc. Sets and reads the I2C SDA line
Bit Mask %0001 0001 0011 1011 ??
Readable Yes
Writable Yes
Subsystem I2C

When write, it sets the SDA line, D0 --> SDA When read, it reads the SDA line, SDA --> D0

Note that I2C uses open collector outputs, the idle, released state is '1'. So if you want to read the line, you have to set it to '1' first.
