//! Initialize AVRCore hardware

//! Set the current external RAM page
//  The AVRCore on-board external RAM is typically 512KBytes.
//  The RAM is memory-mapped into the 32KByte address space from
//  0x8000-0xFFFF, and must therefore be accessed in pages (32KB chunks).
//  Use this function to select which of the 16 (0-15) 32KByte pages
//  you wish to access.

//! Set the state of the four LEDs on AVRCore
//  leds bit0 => LED1 (0=off, 1=on)
//  leds bit1 => LED2 (0=off, 1=on)
//  leds bit2 => LED3 (0=off, 1=on)
//  leds bit3 => LED4 (0=off, 1=on)
void avrcoreSetLeds(u08 leds);

//! Turn on selected LEDs
//  '0' bit = no change
//  '1' bit = turn on
void avrcoreSetLedsOn(u08 leds);

//! Turn off selected LEDs
//  '0' bit = no change
//  '1' bit = turn off

//! Set on/off power setting of AVRCore serial port
//  (0=off, 1=on)
