OverviewMPC5606S Microcontroller Reference Manual, Rev. 770 Freescale SemiconductorIn general, when an individual module is enabled for use, all of the detail required to configure and operateit is contained in the dedicated chapter. In some cases there are multiple implementations of this module;however, there is only one chapter for each type of module in use. For this reason, the address of registersin each module is normally provided as an offset from a base address that can be found in Chapter 2,Memory Map. The benefit of this approach is that software developed for a particular module can be easilyreused on this device and on other related devices that use the same modules.The steps to enable a module for use vary, but typically require configuration of the integration features ofthe microcontroller. The module will normally have to be powered and enabled at the system level, then aclock may have to be explicitly chosen, and finally, if required, the input and output connections to theexternal system must be configured.The primary integration chapters of the reference manual contain most of the information required toenable the modules. There are special cases where a chapter may describe module functionality and someintegration features for convenience — for example, the microcontroller input/output (SIUL) module.Integration and functional content is provided in the manual as shown in Table 1-6.Table 1-6.
