extended code were received.
When the address does not match, an unused interrupt request is not generated, and efficient processing is
possible.
When the start condition is detected, the wake-up standby function is entered. Since the master can become a
slave in an arbitration failure (when a start condition was output), the wake-up standby function is entered while the
address is transmitted.
However, when the stop condition is detected, the generation of interrupt requests is enabled or disabled based
on the setting of bit 5 (SPIE0) in I
