Configure required pins for trace output
1. Create a file for the device
/*------------------------------------------------------------------- ** Define the function to enable the trace port **-----------------------------------------------------------------*/ FUNC void EnableTPIU(void) { _WDWORD(0x40086790, 0x00000032); // Configure PF_4 AS FUNC2 _WDWORD(0x40086794, 0x00000033); // Configure PF_5 as FUNC3 _WDWORD(0x40086798, 0x00000033); // Configure PF_6 as FUNC3 _WDWORD(0x4008679C, 0x00000033); // Configure PF_7 as FUNC3 _WDWORD(0x400867A0, 0x00000033); // Configure PF_8 as FUNC3 } /*------------------------------------------------------------------- ** Invoke the function at debugger startup **-----------------------------------------------------------------*/ EnableTPIU();
2. Set the file as initialization file
