the MRM address map.
The reset states shown for the MRM registers are for the generic (blank ROM) ver-
sions of the device. Several MRM register bit fields can be user-specified on a custom
masked ROM device. Contact a Freescale sales representative for information on or-
dering 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
