Bit Counter 2 to 0
These bits specify the number of bits to be
transferred next. When read, the remaining
number of transfer bits is indicated. The data is
transferred with one addition acknowledge bit. Bit
BC2 to BC0 settings should be made during an
interval between transfer frames. If bits BC2 to
BC0 are set to a value other than 000, the setting
should be made while the SCL line is low. The
value returns to 000 at the end of a data transfer,
including the acknowledge bit.
