R/W Description
R/W Bit Counter 2 to 0
R/W These bits specify the number of bits to be transferred next.
R/W
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.
