With this mechanism, a certain number of interrupt routines (or other routines) can
perform page changes without reading and storing the previously used page information.
The use of only write operations makes the system simpler and faster. Consequently,
this mechanism significantly improves the performance of short interrupt routines.
The XC878 supports local address extension for:

Overwrite the contents of PAGE with the contents of STx, ignoring the value written
to the bit positions of PAGE
(this is done at the end of the interrupt routine to restore the previous page setting
before the interrupt occurred)
