The closest memory for the FC is the FC TCDM and is referred in the API as the FC L1 memory.

All functions transfering data between an external device and a chip memory must use the L2 memory for the chip memory.

The cluster controller is core 0 of the cluster. Core 1 to 7 are the slave cores.

Up to 8 cluster DMA counters can be allocated at the same time. Trying to allocate one more will stall the core.

With the I2S driver, When using 2 RX channels on the same interface (left and right), the buffer contains the samples for both channels interleaved one by one.

I2S buffers size must be a most 64KB - 4.

PI_SPI_WORDSIZE_16 is not supported.
