The registers can conceptually be treated as a single 32-bit register. Theread-only registers provide the following options of the peripheral:Part number [11:0]This identifies the peripheral. The three digit product code 0x804is used for the timer.Designer [19:12] This is the identification of the designer. ARM Limited is 0x41,ASCII A.Revision number [23:20]This is the revision number of the peripheral. The revision numberstarts from 0.Configuration [31:24]This is the configuration option of the peripheral. Theconfiguration value is 0.Figure 4-23 shows the register bit assignments.Actual register bit assignmentConfigurationRevisionnumberDesigner1Designer0Partnumber 1Partnumber 07 0 7 4 3 0 7 4 3 0 7 0Conceptual register bit assignment31 24 23 20 19 16 15 12 11 8 7 0ConfigurationRevisionnumberDesignerPart numberFigure 4-23 Peripheral identification register bit assignments4-34 Copyright © 2003, 2007 ARM Limited.
