(4) Stop condition generation

When SBI0SR

= 1, the sequence for generating a stop condition is started by

writing “111” to SBI0CR2 and “0” to SBI0CR2. Do not modify
the contents of SBI0CR2 until a stop condition has been
generated on the bus. When the bus’s SCL line has been pulled low by another device,
the TMP92CM22 generates a stop condition when the other device has released the
SCL line and SDA pin rising.
