Reserved.
Returns the running count of the PM timer. This counter runs
off a 3.579545 MHz clock (14.31818 MHz divided by 4). It is
reset to zero during a PCI reset, and then continues counting
as long as the system is in the S0 state.
Anytime bit 22 of the timer goes HIGH to LOW (bits
referenced from 0 to 23), the TMROF_STS bit is set. The
High-to-Low transition will occur every 2.3435 seconds. When
the TMROF_EN bit is set, an SCI interrupt is also generated.

Software may set this bit to force the thermal throttling
function. This has the same effect as the THRM# signal being
active for 2 seconds.
0 = No forced throttling.
