23 / 54 page  NXP Semiconductors TDF8599B I2C-bus controlled dual channel 43 W/2 Ohm, single channel 85 W/1 Ohm class-D power amplifier with load diagnostics TDF8599B All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2016. All rights reserved. Product data sheet Rev. 2 — 23 August 2016 23 / 54 In non-I2C mode or when IB3[D7] = 0, the information on the MOD and ADS pins is latched when one of the TDF8599B’s outputs starts switching. STOP START 001aai792 SCL SDA Mµp SLAVE (1) (1) When SCL is HIGH, SDA changes to form the start or stop condition. Figure 22. I2C-bus start and stop conditions SCL SDA 001aai793 (2) (1) Mµp SLAVE (1) SDA is allowed to change. (2) All data bits must be valid on the positive edges of SCL. Figure 23. Data bits sent from Master microprocessor (Mµp) 001aai794 LSB + 1 LSB + 1 LSB MSB - 1 MSB MSB - 1 MSB ACK ACK ACK(1) ACK STOP WRITE DATA WRITE START ADDRESS 1 2 7 8 9 7 8 9 1 2 SCL SDA Mµp SLAVE (1) To stop the transfer after the last acknowledge a stop condition must be generated. Figure 24. I2C-bus write 001aai795 LSB + 1 LSB + 1 LSB MSB - 1 MSB MSB - 1 MSB ACK ACK(1) ACKNOWLEDGE STOP READ DATA READ START ADDRESS 1 2 7 8 9 7 8 9 1 2 SCL SDA Mµp SLAVE (1) To stop the transfer, the last byte must not be acknowledged (SDA is HIGH) and a stop condition must be generated. Figure 25. I2C-bus read 9.1 Instruction bytes If R/W bit = 0, the TDF8599B expects three instruction bytes: IB1, IB2 and IB3. After a power-on reset, all unspecified instruction bits must be set to zero. |
