Initial
Value R/W Description
0 R/W Bit Counter 2 to 0
0 R/W These bits specify the number of bits to be transferred
next. When read, the remaining number of transfer bits is
0 R/W
indicated. With the I
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 pin is low. The value returns to 000 at the end of a
data transfer, including the acknowledge bit. With the
clock synchronous serial format, these bits should not be
modified.
