I am trying to program the device FRAM. i see in the spec sheet we have debug pins available. 
I see we have Spy-Bi-Wire and JTAG interface to program the device.
Just wanted to confirm which interface can be used to program the device efficiently?
Also i see that TCLK and TDI have same pin 22 assigned. Can it be confirmed if it is correct?
If yes how can the pins be used for JTAG operation?
