2.5 Random-Access Memory (RAM)
The 128 bytes of random-access memory (RAM) are located at addresses $0080–$00FF. The location
of the stack RAM is programmable. The 16-bit stack pointer allows the stack to be anywhere in the
64-Kbyte memory space.
Before processing an interrupt, the central processor unit (CPU) uses five bytes of the stack to save the
contents of the CPU registers.
During a subroutine call, the CPU uses two bytes of the stack to store the return address. The stack
pointer decrements during pushes and increments during pulls.
Freescale Semiconductor
Vector Priority
For correct operation, the stack pointer must point only to RAM locations.
For M6805, M146805, and M68HC05 compatibility, the H register is not
stacked.
Be careful when using nested subroutines. The CPU may overwrite data in
the RAM during a subroutine or during the interrupt stacking operation.
