2.4 ROM Security Feature
A security1 feature has been incorporated into the MC68HC05C12A to
help prevent externally reading of code in the ROM. This feature aids in
keeping customer developed software proprietary.
1. No security feature is absolutely secure. However, Motorola’s strategy is to make reading or
copying the ROM difficult for unauthorized users.
2.5 Random-Access Memory (RAM)
The user RAM consists of 176 bytes and is used both for general-
purpose RAM and stack area. The stack begins at address $00FF. The
stack pointer can access 64 bytes of RAM in the range $00FF to $00C0.
NOTE:
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.
