Description
IIC Control Part Reset
This bit resets control parts except for I
registers. If this bit is set to 1 when hang-up is
occurred because of communication failure during
I
setting ports and initializing registers.
Reserved
This bit is always read as 1.
Description
Reserved
The write value should always be 0.
Wait Insertion
This bit selects whether to insert a wait after data
transfer except for the acknowledge bit. When
WAIT is set to 1, after the fall of the clock for the
final data bit, low period is extended for two
transfer clocks. If WAIT is cleared to 0, data and
acknowledge bits are transferred consecutively
with no wait inserted.
The setting of this bit is invalid in slave mode.
Reserved
These bits are always read as 1.
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.
0: When writing, values of BC2 to BC0 are set.
1: When reading, 1 is always read.
2
C operation, I
When writing, settings of BC2 to BC0 are
invalid.
