(1)
This section introduces the MC68HC08JB16, the ROM part equivalent to the
MC68HC908JB16. The entire MC68HC908JB16 data book applies to this
ROM device, with exceptions outlined below.
Figure 5
Figure 6
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.
The monitor program (monitor ROM, $FE10–$FFCF) on the MC68HC08JB16
is for device testing only.
