What are the maximum number of channels select in TDM mode?
There are total 16 individually configurable HSPORT(0A-7A and 0B-7B) in ADSP-21584, each HSPORT can select 128 channels. It means that total 128*16 = 2048 channels are selectable. Is it correct?
On the hardware manual, on page 34-33, it is written that
"In multichannel mode, the SPORT can selectively transfer data on up to a maximum window size of 128 continuous
channels out of a maximum 1024-channel frame while ignoring all the disabled channels within the window
and all the channels outside the window. "
Why selectable channels are limited to 1024? Is there any limitation to select channels (apart from clocking)?
