特性- DSP block :16-bit DSP coreNoise-cancellation processing, filter processingPower-save mode (oscillation stop, PLL stop, switching between high-speed operation and low-speed operation)
- Host CPU interface (4-line system or I2C bus format) :Slave (also used as GPIO0 to 3, GPIO13 to 14)
- Serial PCM interface (4-line system) :2 systems of master and slave (also used as GPIO4 to 7, GPIO10 and 11)I2S, left justified, long frame synchronization, short frame synchronization: Fs=8 kHz supported in master mode
- GPIO :16 ports (also used as host CPU interface and serial PCM interface)
