Figure 15-26 shows the communication reservation timing.
Remark
Communication reservations are accepted via the timing shown in Figure 15-27. After bit 1 (STD0) of the IICA
status register 0 (IICAS0) is set to 1, a communication reservation can be made by setting bit 1 (STT0) of the IICA
control register 0 (IICACTL0) to 1 before a stop condition is detected.
Figure 15-28 shows the communication reservation protocol.
