/*
|
||||
* Standardized way to define a group of registers and corresponding data structures. To define
|
||||
* a new register set, first define struct containing an enumeration called "Id" containing
|
||||
* all register IDs and a template struct called "Struct". Specialize the Struct struct for any
|
||||
* register ID which needs to be accessed in a specialized way. You can then declare the object
|
||||
* containing all register values using the RegisterSet<BaseType, DefiningStruct> type, where
|
||||
* BaseType is the underlying type of each register (e.g. u32).
|
||||
* Of course, you'll usually want to implement the Struct template such that they are of the same
|
||||
* size as BaseType. However, it's also possible to make it larger, e.g. when you want to describe
|
||||
* multiple registers with the same structure.
|
||||
*
|
||||
* Example:
|
||||
*
|
||||
* struct Regs {
|
||||
* enum Id : u32 {
|
||||
* Value1 = 0,
|
||||
* Value2 = 1,
|
||||
* Value3 = 2,
|
||||
* NumIds = 3
|
||||
* };
|
||||
*
|
||||
* // declare register definition structures
|
||||
* template<Id id>
|
||||
* struct Struct;
|
||||
* };
|
||||
*
|
||||
* // Define register set object
|
||||
* RegisterSet<u32, CommandIds> registers;
|
||||
*
|
||||
* // define register definition structures
|
||||
* template<>
|
||||
* struct Regs::Struct<Regs::Value1> {
|
||||
* union {
|
||||
* BitField<0, 4, u32> some_field;
|
||||
* BitField<4, 3, u32> some_other_field;
|
||||
* };
|
||||
* };
|
||||
*
|
||||
* Usage in external code (within SomeNamespace scope):
|
||||
*
|
||||
* For a register which maps to a single index:
|
||||
* registers.Get<Regs::Value1>().some_field = some_value;
|
||||
*
|
||||
* For a register which maps to different indices, e.g. a group of similar registers
|
||||
* registers.Get<Regs::Value1>(index).some_field = some_value;
|
||||
*
|
||||
*
|
||||
* @tparam BaseType Base type used for storing individual registers, e.g. u32
|
||||
* @tparam RegDefinition Class defining an enumeration called "Id" and a template<Id id> struct, as described above.
|
||||
* @note RegDefinition::Id needs to have an enum value called NumIds defining the number of registers to be allocated.
