This is release 1.0 of the ENG_POS API and example files.
The user should refer to Application Note AN3769 "Using the Engine Position 
eTPU Function" which is available from Freescale.

    eng_pos\MPC563M_intram.dld         Rev : 1.1 - Linker file.
    eng_pos\makefile                   Rev : 1.4 - A GNU makefile used to build the example
                                                   code.

NB The example referred to above is a very simple example which uses the tooth 
generation function to provide an input stimulus to the engine position functions.
This is a an example provided in addition to the more complex example referred to 
in AN3769 "Using the Engine Position (CRANK and CAM) eTPU Functions".
In order to use this simple example short eTPU_A0 to eTPU_A1 and short 
eTPU_A14 to eTPU_A15. This connects the tooth generator outputs to the engine
position inputs. This example produces no output. It simply generates a TCR2 (angle clock).


The following files are needed in order to compile and use the example code:
