The MC68HC05X4 has an 8K byte memory map consisting of MCAN
control registers, user ROM or EPROM , user RAM, bootloader ROM,
and I/O (as illustrated in
The user RAM consists of 176 bytes of memory space shared with a 64
byte stack area. The stack begins at address $00FF. The stack pointer
can access 64 bytes of RAM in the range $00C0 to $00FF.
Using the stack area for data storage or temporary work locations
requires care, to prevent the data from being overwritten due to stacking
from an interrupt or subroutine call.
