According to the ADSP-BF537 Blackfin Processor Hardware Reference page 7-34 "It contains a count of how many PPI_CLK cycles to delay after assertion of PPI_FS1 before starting to read in or write out data."
I'd like a delay of 0, but the document says that "reset = 0x0000". So what does `PPI_DELAY = 0x0000;` actually do? What is the correct setting for a delay of 0?
FYI, I'm using a BF537, but I expect this probably applies to many BF chips.
Thanks in advance.
