MC68HC000FN10

Addendum to M68000 User Manual

Motorola => Freescale 

An example trap routine is as follows:

TRAP_x MOVE.B #0,$low_power_address

STOP #$2000

RTE

/* Write that causes ADDRESS_MATCH to assert */

/* STOP instruction with desired interrupt mask */

/* Return from the exception */

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.

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.”
