This bit controls the enable/disable the internal amplifier for external crystal oscillator.
0 = Internal amplifier is enabled.
1 = Internal amplifier is disabled.
Set the XTOFF bit to “1” when user wants to use P1[0] and P1[2] as general I/O pins.
Don’t set XTOFF bit to “1” when XT/RG bit (EXIF.3) is “1”.
(XT/RG = “1” : The external clock is selected as system clock. Refer to EXIF register.)
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
