and $1FF3 — are general-purpose user EPROM locations. Location
$1F00 is the mask option register (MOR).
The contents of the EPROM cannot be prevented from being viewed
externally, since security is not incorporated into the MC68HC705CT4.
2.5 Random-Access Memory (RAM)
The user RAM consists of 256 bytes of a shared stack area. The RAM
starts at address $0030 and ends at address $012F. 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.
