Description
Bit Counter 2 to 0
These bits specify the number of bits to be transferred next.
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 bit counter is initialized to 000 when a start condition is
detected. The value returns to 000 at the end of a data
transfer.
