0 (Default), 1 = Power-down mode enable.
the clock to the peripherals and interrupt blocks is not stopped, and these blocks
continue operating.
0 (Default), 1 = Idle mode enable.

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.
Setting this bit causes the MiDAS1.1 family to go into the IDLE mode.
In this mode the clocks to the CPU are stopped, so program execution is frozen. But
