When POR (Power-On Reset), this bit will be set to “1” by H/W.
For
Setting this bi causes the MCU (MiDAS1.1 family) to go into the power-down mode.
In this mode, all the clocks are stopped and program execution is frozen.
0 (Default), 1 = Power-down mode enable.
0 = The band-gap reference (LVD) will do not run in power-down mode,
1 = The band-gap reference (LVD) will run in power-down mode.
the band-gap reference provides significant power savings in power-down mode, but
sacrifices the ability to perform power-fail reset while stopped.

This bit enables/disables the band-gap reference during power-down mode. Disabling
