This port is based on the C164-ci port by Michael Awosika.
    
--------------------------------- TEST HARDWARE -------------------------------
The current version of the Infineon C167 port has been tested on the:

   Phytec Kit-CON-167 Development Board

Using the Tasking CrossView debugger.


-------------------------------- C167 PORT NOTES ------------------------------

1) The port consists of the following directories:
   
      
   \SOFTWARE\uCOS-II\C167\TASKING\SOURCE
       This directory contains the port source files.
       
   \SOFTWARE\uCOS-II\C167\TASKING\TEST
       This  directory contains a simple test program (TEST.C) consisting of
       two tasks communicating via two Mailboxes. One task counts from 0 to 10 and
       sends this information to the other task which displays the current number on the
       leds of P2 of the Kit-Con-167 board. The file TEST.ABS in the EDE (see below)
       directory is the file used to debug the application. The file Intel-Hex file 
       TEST.HEX can be directly used to download the programm to the flash ROMs on
       the target system. The File assumes that the ROM is located in the lower 4 segs (0-3)
       and the RAM is located in seg 4. This is the standard memory mapping of the Kit-CON board
   
   \SOFTWARE\uCOS-II\C167\TASKING\EDE
       This  directory contains  TASKING Embedded Development Environment (EDE)
       files that were used to build and debug the port. The EDE Project assumes that Tasking is installed on           d:\C166 and the test application is located in c:\software\ucos-ii\C167\Tasking\ede
   
2) You  MUST modify the function prototypes of  OSCtxSw()  and  OSTickISR() in
   uCOS_II.H (see \SOFTWARE\uCOS-II\SOURCE) as follows:

      #ifndef   OS_ISR_PROTO_EXT
      void      OSCtxSw(void);
      void      OSTickISR(void);
      #endif

3) You  MUST modify the function  prototypes of  OSTaskStkInit()  in  uCOS_II.H 
   (see \SOFTWARE\uCOS-II\SOURCE) as follows:

   OS_STK *OSTaskStkInit(void (*task)(void *pd), void *pdata, OS_STK *ptos, INT16U opt);

4) You MUST modify the value of OS_TICKS_PER_SEC from 91 to 38
   (see \SOFTWARE\uCOS-II\SOURCE) as follows:

   #define OS_TICKS_PER_SEC          38   /* Set the number of ticks in one second */

5) The port uses GPT3 to generate the tick. Therefore this timer must not be used by your application.
