AVR Emulator of IC AY-8910, AY-3-8910, AY-3-8912 for Atmega8
Version 17.1 (19.11.2014) 8 MHZ 2 Channel Version for internal oscillator

NON BLOCK INTERRUPT VERSION !!!

New serial protocol from version 14.0
- Baud Rate: 57600
- Data Bits: 8
- Stop Bits: 1
- Parity: NONE
- Registers sent as 2 values 1) Register number 0-13, 2) Register value
- To synchronize, just send 0xFF at start sending

Features:

- Complete chip emulation
- Read mode support (Absolutely correct)
- Parallel mode support
- Serial mode support using pin 2 (RX) at speed 57600
- Very fast INT interrupts for parallel mode
- Very fast timer interrupt

Uploading:

	Use avrdude and USBAsp programmer

	avrdude -b 19200 -p atmega8 -c USBasp -U flash:w:emul8mhz.hex -U lfuse:w:0x24:m -U hfuse:w:0xC7:m


files emulXXmhz_nb.hex 		- standard versions with non blocking interrupts parallen & serial mode

files emulXXmhz_nb_p.hex 	- standard versions with non blocking interrupts parallel mode only support!!!

files emulXXmhz_nb_p_alt.hex	- alternate versions with non blocking interrupts
				  with swapped D6 & D5 data bits (made for 256K upgrade PCB) parallel mode only!!!


I'm not sure if it will work in parallel mode, but in serial mode it works!
