2 BC2 0
1 BC1 0
0 BC0 0
Description
R/W Bit Counter 2 to 0
R/W These bits specify the number of bits to be transferred
next. Bit BC2 to BC0 settings should be made during an
R/W
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 B'000 when a start condition
is detected. The value returns to B'000 at the end of a data
transfer.
