Bit Counter 2 to 0
These bits specify the number of bits to be transferred
next. With the I
2
C 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.
