61notes from DEMUL team
62
63Smashing Drive needs a working SH4 MMU emulation, ATV Track does not.
64
65Audio - is a simple buffered DAC.
66frequency is 32kHz
67data written by CPU to buffer have such meaning:
68offs 0 - s16 bass channel 0
69offs 2 - s16 bass channel 1
70offs 4 - s16 left channel
71offs 6 - s16 right channel
72and so on
73
74buffer is 2x32bytes
75then it becomes (I suppose half) empty - SH4 IRL5 IRQ generated
76
77
78"control registers" (Smashing Drive)
790 - read - various statuses, returning -1 is OK
80write - enable slave CPU, gpu, etc most of bits is unclear
814 - r/w - communication port (for cabinet linking), returning 0 is OK
82also there some bits on SH4 PDTRA port, I'll hook it later by myself
83
84about clocks - SH4s is clocked at 33000000*6
85but unlike to DC/AW/Naomi SH4 'peripheral clock' (at which works TMU timers and other internal stuff) is 1/6 from CPU clock, not 1/4
