Enumeration Type Documentation

enum memMapType

possible memory Types

Enumerator:

MMAP_T_UNUSED	marker memMap entry is free for use
MMAP_T_FLASH	marker memMap entry type is FLASH-EEPROM (e.g. program text and data)
MMAP_T_APPLICATION_FLASH	marker memMap entry type is FLASH-EEPROM (e.g. application data)
MMAP_T_ROM	marker memMap entry type is ROM (e.g. program text and data)
MMAP_T_RAM	marker memMap entry type is RAM
MMAP_T_REREAD_ROM	marker memMap entry type is ROM (invalidate cache data on go)
MMAP_T_UNREAL	marker memMap entry type is pseudo RAM (exists in emulator, but not in real target hardware)
MMAP_T_SFA	marker memMap entry type is Special Function Area (e.g. on chip peripherie register)
MMAP_T_IO	marker memMap entry type is non accessable IO Area (e.g. on chip peripherie register)
MMAP_T_WORKSPACE	marker memMap entry type is RAM (debugger can load its own target program to here)
MMAP_T_CACHE	marker memMap entry type is RAM - used by cache system
