8 Register configuration for the peripheral Electrical specification tables providing the specified limits of the chip when tested under the conditionsdefined in the Recommended operating conditions on page Peripheral naming and abbreviationsEvery peripheral has a unique capitalized name or an abbreviation of its name, TIMER, used foridentification and reference. This name is used in chapter headings and references, and it will appear in theARM Cortex Microcontroller Software Interface Standard (CMSIS) hardware abstraction layer to identifythe peripheral instance name, which is different from the peripheral name, is constructed using theperipheral name followed by a numbered postfix, starting with 0, for example, TIMER0.

9 A postfix is normallyonly used if a peripheral can be instantiated more than once. The peripheral instance name is also used inthe CMSIS to identify the peripheral Register tablesIndividual registers are described using register tables. These tables are built up of two sections. The firstthree colored rows describe the position and size of the different fields in the register. The following rowsdescribe the fields in more Fields and valuesThe Id (Field Id) row specifies the bits that belong to the different fields in the blank space means that the field is reserved and that it is read as undefined, and must be written as 0 tosecure forward compatibility.

10 If a register is divided into more than one field, a unique field name is specifiedfor each field in the Field a field has enumerated values, then every value will be identified with a unique value id in the Value Idcolumn. Single-bit bit fields may, however, omit the Value Id when values can be substituted with a Booleantype enumerator range, for example, True/False, Disable/Enable, On/Off, and so are usually provided as decimal or hexadecimal. Hex values have a '0x' prefix, decimal values haveno Value column can be populated in the following ways: Individual enumerated values, for example, 1, 3, 9. Range of values, [ ], that is, all values from and including 0 and 4.
