General Release Specification — MC68HC05E1
Section 5. Memory
5.1 Contents
5.2 Introduction
The MC68HC05E1 has an 8K byte memory map, consisting of user
ROM, user RAM, Self-Check ROM, Control Registers, and I/O. See
Figure 5-1 and Figure 5-2.
5.3 ROM
4096 bytes of user ROM are located from $0F00 to $1EFF, with 16
additional bytes of user vectors from $1FF0 to $1FFF. The Self-Check
ROM and vectors are located from $1F00 to $1FEF.
5.4 RAM
The user RAM consists of 368 bytes from location $0090 to $01FF
including the stack area. The stack begins at address $00FF. The stack
pointer can access 64 bytes of RAM from $00FF to $00C0. Using the
stack area for data storage or temporary work locations requires care to
prevent it from being overwritten due to stacking from an interrupt or
subroutine call.
