A.5 Mask Option Register
The mask option register at $FFD0 is read only. The value is defined by mask option (hard-wired
connections) specified at the time as the ROM code submission.
On the MC68HC908JL8, the MOR is implemented as a FLASH, which can be programmed, erased, and
read.
A.6 Monitor ROM
The monitor program (monitor ROM: $FE10–$FFCE) on the MC68HC08JL8 is for device testing only.
$FC00–$FDFF are unused.
A.7 Electrical Specifications
Electrical specifications for the MC68HC908JL8 apply to the MC68HC08JL8, except for the parameters
indicated below.
