Get error trap address

[arco]

For an application with a 24FJ128GB108 I get Address Trap errors on irregular basis.
I want to trap the address where it happens and tried this code I found somewhere, but it doesn't return correct address, always 0x00000010

Code: Select all

Dim TrapAddr As LongWord

Sub procedure address() iv IVT_ADDR_ADDRESSERROR ics ICS_AUTO
  asm
    sub w15, #4, w0
    mov [w0++], w1
    mov w1, _trapaddr
    mov [w0], w1
    and #0x7f, w1
    mov w1, _trapaddr+2
  end asm
  AddrErr_bit = 0
end sub

What am I doing wrong?
How many words are pushed on stack before a trap call?

This works! (seems 18 parms are pushed on stack...)

Code: Select all

 
Sub procedure address() iv IVT_ADDR_ADDRESSERROR ics ICS_AUTO
  asm
    mov w15, w0
    sub #36,w0
    mov [w0++], w1
    mov w1, _trapaddr
    mov [w0], w1
    and #0x007f, w1
    mov w1, _trapaddr+2
  end asm
  AddrErr_bit = 0
end sub
