The recommended power-up sequence is to apply VDD first, followed by VDDIO, and then the clock signal. This ensures proper device initialization and prevents damage to the device.
The CS43L43-KZZ can be configured for master or slave mode by setting the M/S bit in the Control Register 1 (CR1). In master mode, the device generates the clock signal, while in slave mode, it receives the clock signal from an external source.
The maximum allowed capacitance for the analog input coupling capacitors is 10uF. Exceeding this value may affect the device's performance and stability.
To optimize the CS43L43-KZZ for low power consumption, set the Power Control Register (PCR) to enable the low-power mode, reduce the clock frequency, and disable unused features such as the PLL and the ADC.
The recommended layout and routing for the CS43L43-KZZ's analog and digital signals is to separate the analog and digital signals, use a ground plane, and minimize the length of the analog signal traces to reduce noise and interference.
