That's the way. And it should even work on 040. To add something new to the topic I give the instruction word if you use an assembler which didn't know about 040/060 instruction. NB: devpac should know it cause it is the same instruction word for 060 and 040.
for both, instruction and data cache:
dc.w $f4f8
just the data cache:
dc.w $f478
just the instrcution cache:
dc.w $f4b8
Little explaination of what CPUSHA does:
All cache (dirty) lines are written to RAM [ obviously just affects the data cache] and then all cahce lines are invalidated, that is are no longer read and overwritten as soon as needed.
CPUSHA is a priviliged instruction as you might exspected.

What's the anti-troll code? That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
