Seta/Allumer X1-010 Emulation core
the chip has 16 voices, all voices can be switchable to Wavetable or PCM sample playback mode.
It has also 2 output channels, but no known hardware using this feature for stereo sound.
Wavetable needs to paired with envelope, it's always enabled and similar as AY PSG's one
but its shape is stored at RAM.
PCM volume is stored by each register.
Both volume is 4bit per output.
Everything except PCM sample is stored at paired 8 bit RAM.
RAM layout (common case: Address bit 12 is swapped when RAM is shared with CPU)
-----------------------------
0000...007f Voice Registers
0000...0007 Voice 0 Register
Address Bits Description
7654 3210
0 x--- ---- Frequency divider*
---- -x-- Envelope one-shot mode
---- --x- Sound format
---- --0- PCM
---- --1- Wavetable
---- ---x Keyon/off
PCM case:
1 xxxx xxxx Volume (Each nibble is for each output)
2 xxxx xxxx Frequency*
4 xxxx xxxx Start address / 4096
5 xxxx xxxx 0x100 - (End address / 4096)
Wavetable case:
1 ---x xxxx Wavetable data select
2 xxxx xxxx Frequency LSB*
3 xxxx xxxx "" MSB
4 xxxx xxxx Envelope period (.10 fixed point, Low 8 bit)
5 ---x xxxx Envelope shape select (!= 0 : Reserved for Voice registers)
0008...000f Voice 1 Register

0078...007f Voice 15 Register
-----------------------------
0080...0fff Envelope shape data (Same as volume; Each nibble is for each output)
0080...00ff Envelope shape data 1
0100...017f Envelope shape data 2

-----------------------------
* Frequency is 4.4 fixed point for PCM,
6.10 for Wavetable.
Frequency divider is higher precision or just right shift?
needs verification.
