2 About this document

This product specification is organized into chapters based on the modules and peripherals that are

available in this IC.

The peripheral descriptions are divided into separate sections that include the following information:

• A detailed functional description of the peripheral

• Register configuration for the peripheral

• Electrical specification tables, containing performance data which apply for the operating conditions

described in Recommended operating conditions on page 436.

2.1 Document naming and status

2.2 Peripheral naming and abbreviations

Every peripheral has a unique capitalized name or an abbreviation of its name, e.g. TIMER, used for

identification and reference. This name is used in chapter headings and references, and it will appear in

the ARM® Cortex® Microcontroller Software Interface Standard (CMSIS) hardware abstraction layer to

identify the peripheral.

The peripheral instance name, which is different from the peripheral name, is constructed using the

peripheral name followed by a numbered postfix, starting with 0, for example, TIMER0. A postfix is

normally only used if a peripheral can be instantiated more than once. The peripheral instance name is

also used in the CMSIS to identify the peripheral instance.
