Description
Reserved
These bits are always read as 1, and cannot be modified.
BC Write Protect
This bit controls the BC2 to BC0 modifications. When
modifying BC2 to BC0, this bit should be cleared to 0 and
use the MOV instruction. In clock synchronous serial
mode, BC should not be modified.
0: When writing, values of BC2 to BC0 are set.
1: When reading, 1 is always read.
Bit Counter 2 to 0
These bits specify the number of bits to be transferred
next. When read, the remaining number of transfer bits is
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.
