See also list of RAM areas by name.
The eZ80 has a 24-bit linear address space. Layout:
- 000000h: Start of flash. The first 128 K are locked boot sectors. The first 8 are divided into 8 K sectors, all of which are locked. Implies that there is no longer a certificate.
- 000066h: Flash exception handler. Write-to-flash without permission triggers the non-maskable interrupt to fire.
- 00007Eh: Hardware/Emu flag: This byte indicates whether the ROM is a hardware ROM or emulator.
- 000080h: Start of boot code jump table.
- D00000h: Start of RAM. 256 K.
- D40000h: Start of VRAM. 320x240x2 bytes = 153600 bytes.
