7 / 10 page —7— CXA1875AP/AM <Registers> In brackets ( ) number of bits REF (1): Switches D/A converter reference voltage 0:Standardizes the inner regulator 1:Standardizes voltage resistance divided from VCC SW0 to 3 (1): Selects ON/OFF of Pins 1, 2, 9 and 10 (Each pin is the open collector output of NPN transistor) 0:OFF 1:ON DAC0 to 4 (8): Digital data input register of D/A converter 0:Output voltage turns to minimum 255:Output voltage turns to maximum PONRES (1): Detects POWER ON RESET 0:Master passes from the bus and is reset to 0 after having read this status 1:Set to 1 when power supply is turned on or when there has been a power dip ST0 to 3 (1): Detects and registers the voltage condition of Pins 1, 2, 9 and 10 0:1.5 V and below 1:3.0 V and above Note) SW0 to 3 effective during 0 I2C Bus Signal There are 2 signals in I2C bus. SDA (Serial DAta) and SCL (Serial Clock). SDA is double-way. • As SDA is double-way it has 3 state outputs, H, L and HIZ. • I2C transfer begins with Start Condition and ends with Stop Condition. L H HIZ L SDA Start Condition S SCL Stop Condition P |
