INITIAL STACK CONFIGURATION
After Reset, the stack is empty. The
empty stack is initialized so the Stack
Pointer is pointing at 0x1F. If the Stack
Overflow Reset if enabled, the TOSH/
TOSL registers will return ‘0’.
If the Stack Overflow Reset is disabled,
the TOSH/TOSL registers will return the
contents of Stack Address 0x0F.
This figure shows the stack
configuration after the first call or
a single interrupt. If a return
instruction is executed, the return
address will be placed in the
Program Counter and the Stack
Pointer
empty state (0x1F).
