Page Selector Field — If DBGEN is set in DBGC1, then 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).
In BKP mode, PAGSEL has no meaning and EXTCMP[5:0] are compared to address bits [19:14] if the address
is in the FLASH/ROM memory space.
Comparator A Extended Compare Bits — The EXTCMP bits are used as comparison address bits as shown
in
FLASH/ROM access
Debug Comparator A Extended Register (DBGCAX)
NOTES:
1. In BKP mode, PAGSEL has no functionality. Therefore, set PAGSEL to 00 (reset state).
2. Current HCS12 implementations are limited to six PPAGE bits, PIX[5:0].
