Reserved Registers
The two registers at $FE08 and $FF09 are reserved locations on the
MC68HC08JB16.
On the MC68HC908JB16, these two locations are the FLASH control register
and the FLASH block protect register respectively.
Monitor ROM
The monitor program (monitor ROM, $FE10–$FFCF) on the MC68HC08JB16
is for device testing only.
