			There are two capture unit slot located at 0x1EC03800. Each slot has 0x10 bytes.

Wwylele: /* 0x1EC03000 */ No, these are not DSP registers, which are located at 1ED03000 (100000 bytes off). RE of CSND command 0x200 also shows that this region has different layout than DSP registers. DSP reigsters are all 2-bytes, while command 0x200 writes 1/4

	The channel registers are based at 0x1EC03400(process virtual address). There's 0x20-bytes total for each channel slot, thus the base-address for a channel's slot is determined with: 0x1EC03400 + (channel_index*0x20). The below offsets are relative to these channel register slots.		The channel registers are based at 0x1EC03400(process virtual address).
