NOTE:
This file defines ALL registers within the device. All registers are named as per
the register names in the relevant data sheet:
Where <register> is the name (in capital letters) of the register, as defined in
the relevant data book (for example, MC9S08GB/D). All registers are defined
as structure types, where the structure name is the same as the register name
with STR appended. For example:
_KBIPE is the actual register. The structures are defined in the header file.
For simplicity, the following examples will use the macro definitions of the
registers.
This file makes available the register definitions for any file that requires access
to the registers. It also maps the registers into the device’s memory map.
The header file contains macros that allow the register to be referenced without
the underscore. For example:
All registers can be referred to by their real definition, in this case “_KBIPE” or
via a macro, in this case “KBIPE”.
The header files supplied with CodeWarrior facilitate access to register bits
through structures and do not include mask-based access to the register bits.
The following example shows the definition of the DBGC register utilizing a
structure.
volatile <register>STR _<register>;
volatile KBIPESTR _KBIPE;
#define KBIPE _KBIPE
