Hello,
Just a little question :
At address $ff8930, there are the following bits :
Source: DMA-PLAYBACK BIT 3 2 1 0
0 - Handshaking on, dest DSP-REC ----------+ | | |
1 - Destination is not DSP-REC ------------' | | |
00 - 25.175Mhz clock -------------------------+--+ |
01 - External clock --------------------------+--+ |
10 - 32Mhz clock -----------------------------+--' |
0 - Handshake on, 1 - Handshake off ----------------'
On DMA Playback, is it possible to have bit 3 = 0 and bit 0 = 1 ?
What happens in this case ?
The same question for address $ff8932 with DMA Record.
I'm sorry to ask, but I haven't got a real falcon to test things and I have to guess everything from very few documentations and code desassembling.
Best regards,
Laurent
