Figure 21.9 Monitor Setup Window - Vector Table Mirroring Tab
Vector Table Mirroring Tab
Using the Vector Table Mirroring tab, it is possible to set the “Vector Table Mirroring”
feature. See the
Vector Redirection section of Freescale Serial Monitor for MC9S08GB/
GT Application Note AN2140/D for all details.
The HCS08 Monitor start address is given in the Monitor Start Address edit box.
The real vector table address is given in the Vector Table Address edit box.
The list of vectors reserved by the HCS08 Serial Monitor is given in the Vectors reserved
by Monitor edit box.
NOTE In the Vectors reserved by Monitor list box above, the number “1” matches the
RESET vector, “2” is the SWI vector, “5” is the ICG vector, etc.
Vector table mirroring allows you to access chip vectors transparently. Indeed, the HCS08
Serial Monitor also uses some vectors, and the vector area is protected from erasing and
overwriting. We recommend that you use this feature. Otherwise, user application vectors
cannot be programmed as captured and are not protected from erasing/overwriting by the
HCS08 Serial Monitor.
To enable this feature, check the Enable Vector Table Mirroring checkbox, then press the
Auto Detect button to make the debugger search for the vector table address and vectors
reserved by the HCS08 Serial Monitor. Once auto detection has succeeded, you can press
the OK button to save and quit this window.
