12 Power Down Operation
12.1 Overview
The MC95FG308 has three power-down modes to minimize the power consumption of the device. In power down
mode, power consumption is reduced considerably. The device provides three kinds of power saving functions, IDLE,
STOP1 and STOP2 mode. In three modes, program is stopped.
