Imagecraft c compiler and development environment for the atmel avr

ICCV8 for AVR – C Compiler for Atmel AVRGreater Than 64K Access FunctionsThese functions are mainly for XMega users to access greater-than-64K-bytes dataand flash program space. The values of the RAMP? registers are preserved. Theirprototype declarations are in AVRdef.h.The extended 5-byte address is specified by ramp, which is the RAMP register value,or the page number, and a 16-bit address.Flash Functions unsigned char FlashReadByte(unsigned char ramp, unsignedaddr)reads a byte from the extended address in flash. unsigned FlashReadWord(unsigned char ramp, unsigned addr)reads a 16-bit word from the extended address in flash. unsigned long FlashReadLWord(unsigned char ramp, unsignedaddr)reads a 32-bit long word from the extended address in flash. void FlashReadBytes(unsigned char ramp, unsigned addr,unsigned char *buf, int n)reads a sequence of bytes from the extended address in flash into a buffer buf inthe lower 64K SRAM address with length n.SRAM Read Functions unsigned char EDataReadByte(unsigned char ramp, unsignedaddr)reads a byte from the extended address in SRAM. unsigned EDataReadWord(unsigned char ramp, unsigned addr)reads a 16-bit word from the extended address in SRAM. unsigned long EDataReadLWord(unsigned char ramp, unsignedaddr)reads a 32-bit long word from the extended address in SRAM. void EDataReadBytes(unsigned char ramp, unsigned addr,unsigned char *buf, int n)108
