Section 15 I
(Only for the H8S/2638, H8S/2639, and H8S/2630)
Bits 2 to 0—Bit Counter (BC2 to BC0): Bits BC2 to BC0 specify the number of bits to be
transferred next. With the I
the data is transferred 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 line is low.
The bit counter is initialized to 000 by a reset and when a start condition is detected. The value
returns to 000 at the end of a data transfer, including the acknowledge bit.
