17.6.5 Stop condition
When the SCL0n pin is high level, changing the SDA0n pin from low level to high level generates a stop condition (n = 0
to 2).
A stop condition is generated when serial transfer from the master device to the slave device has been completed.
When used as the slave device, the start condition can be detected.

Remark n = 0 to 2
A stop condition is generated when the IICCn.SPTn bit is set to 1. When the stop condition is detected, the IICSn.SPDn
bit is set to 1 and the interrupt request signal (INTIICn) is generated when the IICCn.SPIEn bit is set to 1 (n = 0 to 2).
