Memory
2.1 Introduction
The CPU08 can address 64 Kbytes of memory space. The memory map, shown in
2.2 Unimplemented Memory Locations
Accessing an unimplemented location can cause an illegal address reset. In the memory map
(Figure
2.3 Reserved Memory Locations
Accessing a reserved location can have unpredictable effects on microcontroller (MCU) operation. In the
Figure 2-1
or with the letter R.
2.4 Input/Output (I/O) Section
Most of the control, status, and data registers are in the zero page area of $0000–$003F, or at
$0440–$0461. Additional I/O registers have these addresses:
