4.3.2 S-BUS/I2C BUS Timing Diagrams
The clock of the S-BUS/I2C BUS of the ST638x
SPI (single master only) has a fixed bus clock fre-
quency of 62.5KHz. All the devices connected to
the bus must be able to follow transfers with fre-
quencies up to 62.5KHz, either by being able to
transmit or receive at that speed or by applying the
clock synchronization procedure which will force
the master into a wait state and stretch low peri-
ods.

Note: The third pin, SEN, should be high; it is not used in the I2C BUS. Logically SDA is the AND of the
S-BUS SDA and SEN.)
