The 768 bytes at addresses $F000–F2EF and $FEF0–$FEFF are utilized by the
monitor ROM.
The address range $F000–F2EF is reserved for the monitor code functions,
FLASH memory programming, and erase algorithms.
The address range $FEF0–$FEFF holds reserved ROM addresses that contain the
monitor code reset vectors.
