Bluetooth® Core Specification

Technical Terms and Abbreviations

The following technical terms and abbreviations are used in this document

Terms or Abbreviations

Description

Active mode

Normal operating mode. The packet transmission and reception procedure of the Bluetooth®

connection and the other internal CPU activities are executed in this mode. Refer to Section 3.6.

Sleep mode

One of the low power modes. The reference clock stops to save power. The Bluetooth®

connection is kept in this mode. Refer to Section 3.6.

Backup mode

One of the low power modes. This mode consumes same or less power than the Sleep mode.

The power supply of the CPU stops as well as the reference clock. Refer to Section 3.6.

Complete mode

One of the operating modes. A host operates this device using TCU commands (Control API in

the GATT/SM layer). Refer to Section 3.4.

Deep Sleep mode

One of the low power modes. This mode saves more power than the Backup mode. The Sleep

clock stops as well as the power supply of the CPU and the reference clock. Refer to Section

3.6.

HCI mode

One of the operating modes. A host operates this device using HCI commands. Refer to Section

3.4.

PMU

Power Management Unit. Integrated PMU controls the power save procedure of this device.

In order to save power, it switches the built-in DC/DC converter and the LDO regulator properly,

and also controls the output voltage at the same time. Refer to Section 3.1 and Section 3.6.

User-App mode

One of the operating modes. A user application is executed by the built-in CPU in this device.

Refer to Section 3.4.

Auto-Advertising function

Advertising packets are transmitted without software control in the Backup mode. This function

enables the packet transmission even in the low power mode.
