10 / 27 page SDA 5642-6/X Semiconductor Group 10 02.97 2.2.3 Write Mode For writing to the VPS decoder, the following format has to be used: Description of Data Transfer (Write Mode) Step1: In order to start a data transfer the master generates a Start Condition on the bus by pulling the SDA line low while the SCL line is held high. Step 2: The bus master puts the chip address on the SDA line during the next eight SCL pulses. Step 3: The master releases the SDA line during the ninth clock pulse. Thus the slave can generate an acknowledge (AS) by pulling the SDA line to a low level. Step 4: The controller transmits the data byte to set the Control register Step 5: The slave acknowledges the reception of the byte. Step 6: The master concludes the data communication by generating a Stop Condition. The write mode is used to set the I2C-Bus control register which determines the operating mode: Control Register: Default: All bits are set to 0 on power-up. The bits T4 through T7 are used for test purposes and must not be changed for normal operation by user software! (0 = normal operation) You may write 00H, 01H, 02H, 03H, 04H, 05H, 06H, 07H, 08H, 09H, 0AH, 0BH, 0CH, 0DH, 0EH, 0FH to the register without efect. This enables the SDA 5642-6 to be used for VPS decoding instead of the SDA 5050 or SDA 5649 without software problems.
