This read-only field returns the running count of the power management timer. This is
a 24-bit counter that runs off of a 3.579545 MHZ clock, and counts in the working
state. The timer is reset and then continues counting until the CLKIN input to the chip
is stopped. If the clock is restarted without an MR reset, then the counter will resume
counting from where it stopped. The TMR_STS bit is set any time the last bit of the
timer (bit 23) goes from 0 to 1 or from 1 to 0. If the TMR_EN bit is set, the setting of
the TMR_STS bit will generate an
