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. With the clock synchronous serial
format, these bits should not be modified.
