Dear Ajith,
unlike the ARM CortexM, the DSC microcontrollers do not enable non-intrusive direct access to memory using JTAG interface. FreeMASTER can still use the P&E Micro interface and JTAG to connect to DSC, but only to access its EOnCE Real-time Data Exchange port. This port is then used for common serial communication similar to SCI UART.
CortexM microcontroller applications do not need any special code to let FreeMASTER to connect and access memory. With DSC, you need to link your application with the FreeMASTER serial driver configured for EOnCE low-level driver. See the fmstr_eonce example in the SDK package and refer to freemaster_cfg.h configuration:
#define FMSTR_TRANSPORT FMSTR_SERIAL // Use serial transport layer
#define FMSTR_SERIAL_DRV FMSTR_SERIAL_56F800E_EONCE // Use JTAG EOnCE RTD unit
The FreeMASTER plug-in which enables the serial communication over P&E Micro JTAG port is named JTAG/EOnCE Commnication Plugin:

Michal
