* cpc_ssa1.h -- Amstrad SSA-1 Speech Synthesiser, dk'Tronics Speech Synthesiser
*
* Created on: 16/07/2011
*
* Amstrad SSA-1 - SP0256-AL2 based Speech Synthesiser and Sound Amplifier
*
* Uses on-board resonator, clocked at 3.12MHz
*
* Decodes only I/O lines A10, A4 and A0
* Official I/O ports:
* &FBEE (read)
* - bit 7: SP0256 Status 1 (SBY)
* - bit 6: SP0256 Status 2 (/LRQ)
*
* &FBEE (write)
* - bits 7-0: SP0256 Allophone number (must be 0x00 to 0x3f, however, all data lines are hooked up)
*
* &FAEE (write)
* - same as above, used because of a bug in the driver software, but still works due to the way the I/O ports are
* decoded on the CPC.
*
* More info and PCB pics at http://www.cpcwiki.eu/index.php/Amstrad_SSA-1_Speech_Synthesizer
*
*
* dk'Tronics Speech Synthesiser - SP0256-AL2 based speech synthesiser
*
* Uses the CPC's clock of 4MHz from pin 50 of the expansion port, gives faster and higher pitched voices than the SSA-1
*
* Official I/O ports:
* &FBFE (read)
* - bit 7: SP0256 Status 2 (/LRQ)
*
* &FBFE (write)
* - bits 5-0: SP0256 Allophone number
*
