The PNX15xx Series Audio In module receives mono or stereo, 8 or 16-bit/sample
audio data and fills memory with an 8 or 16-bit data structure. The data structure is
put in memory according to both endian mode laws.
A programmer’s view of the Audio In function is sketched in
programmer sees the address of each item (according to the DMA rule), and expects
that 16-bit values are correctly stored in memory according to the CPU law. The DMA
logic of the Audio In module therefore needs to write data in memory (byte) locations
precisely, per
registers of the Audio In module per
the same bit-layout in the CPU register, regardless of endian mode.
