Flash Low Power Mode Enable
Flash Low Power Mode is disabled.
Flash Low Power Mode is enabled. The Flash will be powered down during idle
periods of the clock and powered up during Flash reads. This bit should only be
set if the frequency of the primary oscillator source is 8 MHz or lower. The reset
value of this bit is controlled by the LPDEN option bit during reset.
