16.5.5 Stop condition
When the SCLA0 pin is at high level, changing the SDAA0 pin from low level to high level generates a stop condition.
A stop condition is a signal that the master device generates to the slave device when serial transfer has been completed.
When the device is used as a slave, stop conditions can be detected.
Figure 16-20. Stop Condition
A stop condition is generated when bit 0 (SPT0) of IICA control register 00 (IICCTL00) is set to 1. When the stop condition
is detected, bit 0 (SPD0) of the IICA status register 0 (IICS0) is set to 1 and INTIICA0 is generated when bit 4 (SPIE0) of the
IICCTL00 register is set to 1.
