As requested long ago, added CoData* parameter to all this applications callback, let application designer use identical callback for multiple nodes, and reduce source code length.

Concerned callbacks :

initialisation
preOperational
operational
stopped
heartbeatError
post_sync
post_TPDO
post_SlaveBootup
storeODSubIndex
post_emcy

/* 
Define the i/o port global symbol 
*/

.globl _io_ports
_io_ports=0x0000	
	
/* 
0x0000 is the default mapping at reset. (it is 0x1000 for 68hc11)
*/
