Refer to the Power Management chapter in the MCF52259 Reference Manual for more information on low-power
modes.

CLKOUT, PST/DDATA signals, and all peripheral clocks except UART0 and CFM off before entering low-power
mode. CLKOUT is disabled.

Results are identical to STOP 00 for typical values because they only differ by CLKOUT power consumption.
CLKOUT is already disabled in this instance prior to entering low-power mode.
