M68000 USER’S MANUAL ADDENDUM
MOTOROLA
An example trap routine is as follows:
TRAP_x
MOVE.B #0,$low_power_address
STOP #$2000
RTE
The first instruction (MOVE.B #0,$low_power_address) writes a byte to the low-power address that will
cause the external circuitry to begin the sequence that will stop the processor’s clock. The second
instruction (STOP #$2000) loads the SR with the immediate data. This lets you set the interrupt that will
cause the processor to come out of the low-power mode. The final instruction (RTE) tells the processor to
return from the exception and resume normal processing.
/* Write that causes ADDRESS_MATCH to assert */
/* STOP instruction with desired interrupt mask */
/* Return from the exception */
3.0 MC68SEC000 ELECTRICAL SPECIFICATIONS
Add to the following table to Section 10.1.
3.1 MC68SEC000 MAXIMUM RATINGS
3.2 CMOS CONSIDERATIONS
The following change should be made to Section 10.4, CMOS Considerations.
“Although the MC68HC000 and MC68EC000 is implemented with input protection diodes, care should be
exercised to ensure that the maximum input voltage specification is not exceeded.” should read “Although
the MC68HC000, MC68EC000, and MC68SEC000 are implemented with input protection diodes, be
careful not to exceed the maximum input voltage specification.”
