Table 4. Summary of MC68HC08JB16 and MC68HC908JB16 Differences
(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.
