Bit Counter 2 to 0
These bits specify the number of bits to be transferred
next. 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 bit counter is initialized to 000 when a start condition
is detected. The value returns to 000 at the end of a data
transfer.
