2.1 Contents
2.2 Introduction
The MC68HC05P18 and MC68HC805P18 both utilize 14 address lines
to access an internal memory space covering 16 Kbytes. This memory
space is divided into input/output (I/O), random-access memory (RAM),
electrically erasable, programmable read-only memory (EEPROM),
read-only memory (ROM), and boot ROM areas.
Figure 2-1 and Figure 2-2 show user mode memory maps for the
MC68HC05P18 and MC68HC805P18, respectively.
2.3 Input/Output and Control Registers
Figure 2-3 and Figure 2-4 briefly describe the input/output (I/O) and
control registers at locations $0000–$001F. Reading unimplemented
bits will return unknown states, and writing unimplemented bits will be
ignored.
