Doesn't LAPIC timer stop when CPU goes to sleep state?

[mnln.l4]

I have FreeBSD 9.0-STABLE r237285, In my systl -a output, I see

kern.eventimer.et.LAPIC.flags: 7

I am under the impression LAPIC timer may stop when CPU goes to sleep
state. Shouldn't the flag be 15 as the example in EVENTTIMERS(4) man
page?

I have H67MA-E35 motherboard with Intel H67 chipset, and G840 dual core CPU.

Thanks.
