Also, in low-speed mode, the on-chip oscillator stops in the QzROM
version regardless of the on-chip oscillator stop bit value. The on-
chip oscillator does not stop in the flash memory version, so set this
bit to “1” to stop the oscillation.
In on-chip oscillator mode, even if this bit is set to “1”, the on-chip
oscillator oscillation does not stop in the flash memory version, but
stops in the QzROM version.
