Description
Bit Counter 2 to 0
These bits specify the number of bits to be transferred
next. With the I
one additional 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
B'000, the setting should be made while the SCL line is
low. The value returns to B'000 when a start condition is
detected or when data transfer including the
acknowledge bit ends.
