RFSTR1, RFSTR0 — Register Following Stretch
EXSTR1, EXSTR0 — External Access Stretch
ROMON28, ROMON32 — Enable bits for ROM
This two bit field determines the amount of clock stretch on accesses
to the 512 byte Register Following Map. It is valid regardless of the
state of the NDRF bit. In Single Chip and Peripheral Modes this bit
has no meaning or effect.
This two bit field determines the amount of clock stretch on accesses
to the External Address Space. In Single Chip and Peripheral Modes
this bit has no meaning or effect.
These bits are used to enable the Flash EEPROM arrays FEE28 and
FEE32 respectively.
0 = Corresponding Flash EEPROM array disabled from the memory
map.
1 = Corresponding Flash EEPROM array enabled in the memory
map.
