7.5 Low-Power Stop Mode Operation

M68HC16 Z SERIES
USER’S MANUAL
Refer to
Low-power stop mode minimizes MCU power consumption. Setting the STOP bit in
MRMCR places the MRM in low-power stop mode. In low-power stop mode, the array
cannot be accessed. The reset state of STOP is the complement of the logic state of
DATA14 during reset. Low-power stop mode is exited by clearing STOP.
Signature registers RSIGHI and RSIGLO contain a user-specified mask-programmed
signature pattern. A user-specified signature algorithm provides the capability to verify
ROM array contents.
The state of the MRM following reset is determined by the default values programmed
into the MRMCR BOOT, LOCK, ASPC[1:0], and WAIT[1:0] bits. The default array
base address is determined by the values programmed into ROMBAL and ROMBAH.
When the mask programmed value of the MRMCR BOOT bit is zero, the contents of
MRM bootstrap words ROMBS[0:3] are used as reset vectors. When the mask pro-
grammed value of the MRMCR BOOT bit is one, reset vectors are fetched from exter-
nal memory, and system integration module chip-select logic is used to assert the boot
ROM select signal CSBOOT. Refer to
information concerning external boot ROM selection.
