C.2 LOW-POWER STOP MODE
The low-power stop mode is a reduced power mode of operation, that causes the
MC68040V and MC68EC040V to remain quiescent until either a reset or non-masked
interrupt occurs. This mode of operation has four phases of operation and is triggered by
the low-power stop (LPSTOP) instruction:
MOTOROLA
1. Perform a LPSTOP broadcast cycle.
2. End integer unit (IU) instruction pipeline sequencing, which is similar to the STOP
instruction sequence (IMM data ˘ SR), at termination of the LPSTOP broadcast
cycle.
