currently i am working on TMDSHVMTRPFCKIT with tms320f28035 control card. but i can not get external interface address line(XA) AND external interface data line(XD) ON this pin configuration,

1. can i use GPIO PIN

2. ALSO RELATED TO THE ABOVE BUT CAN I CONNECT EXTERNAL DAC (AD7305 IC) TO TMDSHVMTRPFCKIT

F28035 doesn't support external data and address lines and doesn't also have such external interface on TMDSHVMTRPFCKIT. You might use SPI as an option to some DAC devices. Of course, you could use GPIO to simulate the external data interface if there is enough GPIOs on board, please refer to the schematic of F28035 controlCard and TMDSHVMTRPFCKIT which could be found in controlSUITE.

from the kit TMDSHVMTRPFCKIT we have DAC PIN, BUT i do not need these rather i want to add AD7305 OR related DAC device and see the output, is that this possible

i have PWM6A,7A,6B,7B OR GPIO 10 ,11,40,41 PIN

This depends on the interface of AD7305, you may use the GPIOs on H2 connection which supports both SPI and I2C. It seems like SPI is more easy to use for this device. And you could find some examples of how to use the SPI in controlSUITE.
