R/W These bits specify the number of bits to be transferred
R/W ^{next. With the I2C bus format, 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.
