3.4.10. PWM Interfaces

In the case of multiplexing, the module supports up to 12 PWM channels. Each PWM channel has three
modes: Timer mode, PWM mode, and Capture mode. Each mode of each channel is multiplexed with
32-bit counting. The PWM running clock can be either high speed clock or low power clock. Each PWM
runs independently with its own duty cycle.

3.4.11. I2S Interface

The module integrates an I2S interface multiplexed with GPIOs. It supports master and slave modes with
sample rates from 8 kHz to 384 kHz. The I2S interface supports both PCM mono channel mode and I2S
stereo channel mode with programmable data width between 1 and 32 bits.
