Stop Condition - NEC 78K0 Series User Manual

17.5.5 Stop condition

When the SCL0 pin is at high level, changing the SDA0 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.
A stop condition is generated when bit 0 (SPT0) of IIC control register 0 (IICC0) is set to 1. When the stop
condition is detected, bit 0 (SPD0) of IIC status register 0 (IICS0) is set to 1 and INTIIC0 is generated when bit 4
(SPIE0) of IICC0 is set to 1.
