FIGURE 3-8:
ACCESSING THE STACK EXAMPLE 4
3.4.2
OVERFLOW/UNDERFLOW RESET
If the STVREN bit in Configuration Word 2 is
programmed to ‘1’, the device will be reset if the stack
is PUSHed beyond the sixteenth level or POPed
beyond the first level, setting the appropriate bits
(STKOVF or STKUNF, respectively) in the PCON
register.
3.5
Indirect Addressing
The INDFn registers are not physical registers. Any
instruction that accesses an INDFn register actually
accesses the register at the address specified by the
File Select Registers (FSR). If the FSRn address
specifies one of the two INDFn registers, the read will
return ‘0’ and the write will not occur (though Status bits
may be affected). The FSRn register value is created
by the pair FSRnH and FSRnL.
The FSR registers form a 16-bit address that allows an
addressing space with 65536 locations. These locations
are divided into three memory regions:
Traditional Data Memory
Linear Data Memory
Program Flash Memory
0x0F
0x0E
0x0D
0x0C
0x0B
0x0A
0x09
0x08
0x07
0x06
0x05
0x04
0x03
0x02
0x01
Return Address
0x00
STKPTR = 0x10
When the stack is full, the next CALL or
an interrupt will set the Stack Pointer to
0x10. This is identical to address 0x00
so the stack will wrap and overwrite the
return address at 0x00. If the Stack
Overflow/Underflow Reset is enabled, a
Reset will occur and location 0x00 will
not be overwritten.
