AVR Emulator of IC AY-8910, AY-3-8910, AY-3-8912 for Atmega8
Version 16.2 (16.11.2014) Extra optimized + absolutely correct 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:emul27mhz.hex -U lfuse:w:0xCE:m -U hfuse:w:0xC5:m

	or

	avrdude -b 19200 -p atmega8 -c USBasp -U flash:w:emul27mhz.hex -U lfuse:w:0x7E:m -U hfuse:w:0xC5:m

files emulXXmhz.hex 		- standard versions support both serial and parallel mode
files emulXXmhz_p.hex 		- standard versions parallel mode only support!!!
files emulXXmhz_alternate_p.hex	- alternate versions with swapped D6 & D5 data bits (made for 256K upgrade PCB) parallel mode only!!!
