Section 17 I
17.3.3
ICMR is an 8-bit readable/writable register that selects whether the MSB or LSB is transferred
first, performs master mode wait control, and selects the transfer bit count.
ICMR is initialized to H'38 by a power-on reset or deep standby mode. Bits BC[2:0] are initialized
to H'0 by the IICRST bit in ICCR2.

Wait Insertion
In master mode with the I
whether to insert a wait after data transfer except 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 with the

format.
Reserved
These bits are always read as 1. The write value should
always be 1.
BC Write Protect
Controls the BC[2:0] modifications. When modifying the
BC[2:0] bits, this bit should be cleared to 0. In clocked
synchronous serial mode, the BC[2:0] bits should not
be modified.
0: When writing, values of the BC[2:0] bits are set.
