System Name: DEBIE DPU SW
|
|
Subsystem : DNI (DEBIE Null Interface)
|
|
Module : keyword.h
|
|
|
|
Macro definitions for Keil specific keywords to be used
|
|
in portable parts of the DEBIE DPU software.
|
|
|
|
This version adapted to the GNU C compiler for the MPC5554.
|
|
|
|
Based on the SSF DHI file keyword.h, revision 1.9, Tue Mar 09 12:37:20 1999.

/* Integer type definitions for native types that can hold integer
|
|
values of at least a given number of bits. These types are used
|
|
as loop counters to give the most natural and speedy code for
|
|
the current target. This is Not the C99 stdint.h, but the types
|
|
have similar names.
|
|
|
|
There is a particular form of this file for each (kind of) target
|
|
processor. The present form is for MPC5554/gcc, where the
|
|
widths the integer types are the following (as observed from the
|
|
code of the function Check_Type_Size in harness.c):
|
|
|
|
Type Octets Bits
|
|
char 1 8
|
|
short 2 16
|
|
int 4 32
|
|
long 4 32
|
|
|
|
This processor/compiler also has alignment concerns, so here we
|
|
define all telemetry data as octets and access it using memcpy()
|
|
instead of direct assignment.
