RESET:
The MRM is used only in the MC68HC16Y3. Table D-20 shows the MRM address
map.
The reset states shown for the MRM registers are for the generic (blank ROM)
versions of the device. Several MRM register bit fields can be user-specified on a
custom masked ROM device. Contact a Motorola sales representative for information
on ordering a custom ROM device.
The reset state of the STOP bit is the complement of DATA14 state during reset. The
ROM array base address cannot be changed unless the STOP bit is set.
This bit may be read or written at any time.
0 = ROM array operates normally.
1 = ROM array operates in low-power stop mode. The ROM array cannot be read
