Memory
2.1 Introduction
The CPU08 can address 64 Kbytes of memory space. The memory map, shown in
2.2 Input/Output I/O Section
Addresses $0000–$005F, shown in
Additional I/O registers have these addresses:
2.3 Monitor ROM
The 1024 bytes at addresses $FA00–$FDFF and 448 bytes at addresses $FE10–$FFCF are reserved
ROM addresses that contain the instructions for the monitor functions. (See
(MON).)
