- The oscillator should be usually 3.12MHz (in practice, it's often different).
- Allows to output sounds up to 5kHz (ie. the output is updated at 10kHz rate).
- The SP0256 is reportedly expandable to "491 K of ROM" (probably bullshit).
- The SP0256B is reportedly expandable to "480 K of ROM" (probably K=Kbits).
- The TEST pin of the SP0256 chip can be used (among others) to dump its internal ROM. Note: Details on TEST are found in the "SP0256B" datasheet - but not in the "SP0256" datasheet - not sure if the pin works identical for both chip types, nor if there's a difference between them at all.
External ROMs
For curiostiy, below are the pin-outs for external speech ROMs (though none of the known speech interfaces for the CPC uses them).
SPR16 (16kbit) and SPR32 (32kbit) - External Serial-bus Speech ROM
1 GND 2 C3 3 NC 4 ROM CLK 5..6 NC 7 CS1 8 /CS2 9 /ROM ENABLE 10 SERIAL OUT 11 VCC 12..13 NC 14 SERIAL IN 15 C1 16 C2
SPR128 (128kbit) - External Serial-bus Speech ROM
1 GND 2 C3 3 NC 4 ROM CLK 5..10 NC 11 CS1 12 /CS2 13 /ROM ENABLE 14 SERIAL OUT 15 VCC 16..21 NC 22 SERIAL IN 23 C1 24 C2
