Device modes

Mode Entry Module is a smart module implemented in SPC560B that intends at saving total

device consumption. In fact it allows to manage different level of low-power modes that can

reach, at minimum, few µA.

2.1

Modes overview

Mode Entry (MC_ME) is a SPC560B module that allows the user to centralize the control of

all device modes and related modules/parameters within a unique module. In this way, it

simplifies the implementation of mode management and thus increases its robustness.

The MC_ME is based on several device modes corresponding to different usage models of

the device. Each mode is configurable and can define a policy for energy and processing

power management to fit particular system requirements. An application can easily switch

from one mode to another depending on the current needs of the system.

SPC560B modes can be subdivided in the following groups:

●

System modes:

All the modes (RESET, TEST, SAFE, DRUN) in which the device must be initialized and

properly configured

●

Running modes:

All the modes (RUN0:3) used to obtain the full device performance

●

Low Power modes:

All the modes (HALT, STOP, STANDBY) used to minimize the power consumption
