M68000 USER’S MANUAL ADDENDUM
MOTOROLA
After the previous steps are completed, the MC68SEC000 will remain in the low-power mode until it
recognizes the appropriate interrupt . External logic will also have to poll IPLB2–IPLB0 to detect the proper
interrupt. When the correct interrupt level is received, the following steps will bring the processor out of the
low-power mode:
1.
Restart the system clock if it was stopped.
2.
Wait for the system clock to become stable.
3.
Assert the RESTART signal. This will cause the processor’s clock to start on the next falling edge of
the system clock. Figure 6 shows the timing for bringing the processor out of the low-power mode.
Both the RESTART and RESET signals are subject to the asynchronous setup time as specified in
the Electrical Characteristics section of this addendum.
WARNING
The system clock must be stable before the RESTART signal is asserted
to prevent glitches in the clock. An unstable clock can cause unpredictable
results in the MC68SEC000.

4.
If the MC68SEC000 was placed in a three-state condition, the BR signal must be negated before the
processor can begin executing instructions.
