What are all the
interrupt vector
numbers for the
MC9S08GB60?
Where are header
files located?
Should I use bit
fields or masks for
bit manipulation?
How does the
compiler use
page 0?
MOTOROLA
The following define statements include ALL the interrupt vectors of the
MC9S08GB60.
Basically, there are two types of header files used within C:
System header files are located within the Metrowerks CodeWarrior
directories; for the HCS08, they are located in the directory “CodeWarrior
CW08_V3.0\lib\HC08c\include”.
User header files are normally located within a sub-directory of the project
directory (for example, Sources or headers). User headers are made available
to the user by adding them to the project.
Metrowerks CodeWarrior will use bit field instructions (bit set, clear,
test/branch) for bit field data or simple mask operations on data within page 0.
For memory other than page 0, the compiler translates bit field operations to bit
mask operations.
Most registers are defined within page 0, and the compiler will utilize direct
addressing wherever possible when using the peripheral registers. The linker
files generated for a device do not use page 0 by default (unless the device only
has RAM in page 0). The default will allocate variables in extended memory.
