Remark
Communication reservations are accepted via the following timing. After bit 1 (STD0) of IIC status register 0
(IICS0) is set to 1, a communication reservation can be made by setting bit 1 (STT0) of IIC control register 0
(IICC0) to 1 before a stop condition is detected.
Figure 18-22 shows the communication reservation protocol.
