In special mode and for test purposes only, the 128K bytes of Flash
EEPROM for MC68HC912DT128A can be accessed through a test
program space window of 32K bytes. This window replaces the user’s
program space window to be able to access an entire array. In special
mode and with ROMTST bit set in MISC register, a program space is
located from $8000 to $FFFF. Only two page indices are used to point
to one of the four 32K byte arrays. These indices can be viewed as
expanded addresses X16 and X15.
Read and write anytime
Writes do not change pin state when pin configured for page index
emulation output.
This port is associated with page index emulation pins. When the port is
not enabled to emulate page index, the port pins are used as general-
purpose I/O. Port K bit 3 is used as a general purpose I/O pin only. This
register is not in the map in peripheral or expanded modes while the
EMK control bit in MODE register is set.
