Number $103B
Decimal 4155
Short desc. Sets and reads the I2C SCL line.
Bit Mask %0001 0000 0011 1011 ??
Readable Yes
Writable Yes
Subsystem I2C

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