(4) Stop condition generation
When SBISR<BB> = “1”, the sequence for generating a stop condition start by
writing “1” to SBICR2<MST, TRX, PIN> and “0” to SBICR2<BB>. Do not modify the
contents of SBICR2<MST, TRX, PIN, BB> until a stop condition has been generated
on the bus. When the bus’s SCL line has been pulled Low by another device, the
TMP92CZ26A generates a stop condition when the other device has released the SCL
line and SDA pin rising.
