10 / 40 page  2000 Jan 24 10 Philips Semiconductors Product specification 5 V mixers/oscillators and synthesizers for cable TV and VCR 2-band tuners TDA6402; TDA6402A; TDA6403; TDA6403A Table 8 Reference divider ratio select bits Note 1. X = don’t care. RSA RSB REFERENCE DIVIDER RATIO FREQUENCY STEP (kHz) X(1) 0 640 6.25 0 1 1024 3.90625 1 1 512 7.8125 READ MODE; R/W = 1 (see Table 9) Data can be read from the device by setting the R/W bit to logic 1. After the slave address has been recognized, the device generates an acknowledge pulse and the first data byte (status byte) is transferred on the SDA line (MSB first). Data is valid on the SDA line during a HIGH-level of the SCL clock signal. A second data byte can be read from the device if the microcontroller generates an acknowledge on the SDA line (master acknowledge). End of transmission will occur if no master acknowledge occurs. The device will then release the data line to allow the microcontroller to generate a STOP condition. The POR flag is set to logic 1 at power-on. The flag is reset when an end-of-data is detected by the device (end of a READ sequence). Control of the loop is made possible with the in-lock flag FL which indicates when the loop is locked (FL = 1). The automatic charge pump switch flag (ACPS) is LOW when the automatic charge pump switch mode is ‘ON’ and the loop is locked. In other conditions, ACPS = 1. When ACPS = 0, the charge pump current is forced to the LOW value. A built-in ADC is available on LOCK/ADC pin (I2C-bus mode only). This converter can be used to apply AFC information to the microcontroller from the IF section of the television. The relationship between the bits A2, A1 and A0 is given in Table 11. Table 9 Read data format Note 1. MSB is transmitted first.
