Serial peripheral interface (SPI)/Inter-integrated sound
interfaces (I2S)
Up to three SPIs are able to communicate at up to 18 Mbits/s in slave and master modes in
full-duplex and half-duplex communication modes. The 3-bit prescaler gives 8 master mode
frequencies and the frame is configurable to 8 bits or 16 bits. The hardware CRC
generation/verification supports basic SD Card/MMC modes.
The SPIs can be served by the DMA controller.
Three standard I2S interfaces (multiplexed with SPI1, SPI2 and SPI3) are available, that can
be operated in master or slave mode. These interfaces can be configured to operate with
16/32 bit resolution, as input or output channels. Audio sampling frequencies from 8 kHz up
to 192 kHz are supported. When either or both of the I2S interfaces is/are configured in
master mode, the master clock can be output to the external DAC/CODEC at 256 times the
sampling frequency. All I2S interfaces can operate in half-duplex mode only.
Refer to Table 9 for the features between SPI1, SPI2 and SPI3.
