16.2.9 Power Control Register (SIM_PWR)
SIM_PWR contains a single control field to enable/disable the standby mode of the
primary voltage regulator.
Address: SIM_PWR – F0E0h base + 8h offset = F0E8h
16.2.10 Clock Output Select Register (SIM_CLKOUT)
SIM_CLKOUT can be used to multiplex selected clocks generated inside the clock
generation, SIM, and other internal modules onto the SIM CLKOUT clock output signal.
This signal, in turn, is typically brought out to an external pad. Glitches may be produced
when the clock is enabled or switched. The delay from the clock source to the output is
unspecified. The visibility of the waveform on the CLKOUT on an external pad is subject
to the frequency limitations of the associated I/O cell.

Large Regulator Standby Control-
Controls the standby mode of the primary on-device voltage regulator. Standby mode reduces overall
device power consumption but places significant constraints on the allowed operating frequency. Refer to
the Power Supervisor module for details on standby mode. The field value can optionally be write
protected.
