ASEL_EMO2 10 DIO Pullup I2C Address Select. Address will 0X34/0X36 with the value of pin being "0' or "1" during de-assertion of reset. Can be programmed to be an output (as energy manager output for subwoofer) AVDD 9 P Analog supply (3.3 V) for PLL. AVDD_PWM 50 P 3.3-V analog power supply for PWM. This terminal can be connected to the same power source used to drive power terminal DVDD; but to achieve low PLL jitter, this terminal should be bypassed to AVSS_PWM with a 0.1- μF low-ESR capacitor. AVSS 5 P Analog ground AVSS_PWM 51 P Analog ground for PWM. Must have direct return Cu path to analog 3.3V supply for optimized performance. BKND_ERR 34 DI Pullup Active-low. A back-end error sequence is generated by applying logic low to this terminal. The BKND_ERR results in no change to I2C parameters, with all H- bridge drive signals going to a hard-mute state (Non PWM Switching). DVDD1 35 P 3.3-V digital power supply. (It is recommended that decoupling capacitors of 0.1 μF and 10 μF be mounted close to this pin). DVDD2 14 P 3.3-V digital power supply for PWM. (It is recommended that decoupling capacitors of 0.1 μF and 10 μF be mounted close to this pin). DVSS1 36 P Digital ground 1 DVSS2 13 P Digital ground 2 EMO1 15 DO Energy Manger Output interrupt - Asserted high when threshold is exceeded.
