/**
* @mainpage General program for ATMEGA128 ZX Evolution.
*
* @section history Revision history
*
* @subsection current Current version.
*
* - Add any (left or right) Ctrl,Alt keys and exclude mapped Ctrl,Alt keys from Ctrl-Alt-Del functionality (reset).
* - Add reading state of LCTRL,RCTRL,LALT,RALT,LSHIFT,RSHIFT,F12 keyboard states from RTC register D (bits 0-6).
* - Add reading state of NUM LOCK LED from RTC register C (bit 0).
* - Fix update_keys function.
* - Add EEPROM access via RTC interface.
* - Add reset PS2 keyboard after error.
* - Fix change resolution command (need for some PS2 mouses).
*
* @subsection ver_2014_04_13 Version 13.04.2014.
*
* - Fix access to users keyboard map.
*
* @subsection ver_2013_11_08 Version 08.11.2013.
*
* - Add mode 60Hz;
* - Fix RS232 (clear overrun error flag).
*
* @subsection ver_2012_02_13 Version 13.02.2011.
*
* - Add SD WRP and SD DET to C gluk's register.
* - Fix PS2 keyboard hangup.
* - Add some controls to C gluk's register.
* - Add access to PS2 keyboards log via gluk extensions.
*
* @subsection ver_2011_09_29 Version 29.09.2011.
*
* - Add support BCD or HEX format in emulation Gluk clock.
* - Fix RTS line control.
*
* @subsection ver_2011_06_11 Version 11.06.2011.
*
* - Add NMI button supporting.
* - Fix PS/2 mouse initialization.
*
* @subsection ver_2011_05_11 Version 11.05.2011
*
* - Direct load UBRR on RS232 mode [if (DLM&0x80)!=0 ].
* - Control PLL (ICS501M) via PE2,PE3. Set it to 2X.
*
* @subsection ver_2011_04_26 Version 26.04.2011
*
* - Add RS232 supporting.
* - Increase delay for reset FPGA (nCONFIG pin) before download it.
*
* @subsection ver_2011_04_02 Version 02.04.2011
*
* - Add access to 0..EF cells of PC8583.
* - Fix RTC PC8583 dayweek 0..6 convert to DS12788 dayweek 1..7 and vice versa.
*
* @subsection ver_2010_12_07 Version 07.12.2010
*
* - Keyboard mapping without using RAM.
* - Add setting resolution for PS/2 mouse [1..4].
* (left and right mouse buttons and pad'*' - default [1], pad'+' - increment, pad'-' - decrement).
* - Add PS/2 mouse resolution saving to RTC register.
*
* @subsection ver_2010_11_29 Version 29.11.2010
*
* - "NumLock" switch mode to beeper/pwm or tapeout ("NumLock" led light on tapeout mode).
* - Create full translation map (0x00-0x7f for extended scan codes).
*
* @subsection ver_2010_10_17 Version 17.10.2010
*
* - "F9","F10","F11" on PS/2 keyboard not used for reset function.
* - "F12" on PS/2 keyboard soft/hard reset. Short press (<5sec) - soft reset, long press (5sec) - hard reset.
* - "Ctrl-Alt-Del" on PS/2 keyboard reset ZX (hard reset). If all keys is mapped to ZX keyboard - function not work.
* - Create translation map (PS/2 to ZX keyboard) in eeprom (default in progmem).
* - Fix PS/2 mouse and keyboard send mode (without 'delay' function).
* - Support load from tape input.
*
* @subsection ver_2010_03_30 Version 30.03.2010
*
* - Fix fpga load and ZX part init (optimize).
*
* @subsection ver_2010_03_28 Version 28.03.2010
*
* - Fix PS/2 mouse error handler (analize error and reinit mouse if need it).
* - Add support for get version info (via Gluk cmos extra registers 0xF0..0xFF).
* - Optimize sources, some correction (log, fpga load).
* - Fix PS/2 timeout error handler.
*
* @subsection ver_2010_03_24 Version 24.03.2010
*
* - Fix Power Led behavior (it off while atx power off).
* - "Print Screen" PS2 keyboard key set NMI on ZX.
* - Soft reset (Z80 only) to service (0) page if pressed "softreset" key <5 seconds.
*
* @subsection ver_2010_03_10 Version 10.03.2010
*
* - Add PS2 keyboard led controlling: "Scroll Lock" led equal VGA mode.
* - Fix mapping gluk (DS12887) nvram to PCF8583.
* - Fix Update Flag in register C (emulation Gluk clock).
* - Add modes register and save/restore it to RTC NVRAM.
* - Add support for zx (mechanical) keyboard.
* - Add support for Kempston joystick.
*
* @subsection ver_2010_02_04 Version 04.02.2010 - base version (1.00 in SVN).
