EXTCMP
See
Current HCS12 implementations have PPAGE limited to 6 bits. Therefore, EXTCMP[5:4] should be set to 00.
Data page (DPAGE) and Extra page (EPAGE) are reserved for implementation on devices that support paged data and extra
space.

Page Selector Field — In both BKP and DBG mode, PAGSEL selects the type of paging as shown in
Table
DPAGE and EPAGE are not yet implemented so the value in bit 7 will be ignored (i.e., PAGSEL values of 10 and
11 will be interpreted as values of 00 and 01, respectively).
Comparator C Extended Compare Bits — The EXTCMP bits are used as comparison address bits as shown
in
