a. A Fast-Mode I2C-bus device can be used in a Standard-Mode I2C-bus system, but the requirement t
ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCL
signal. If such device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA
line t
SCL line is released.
