I am fairly confused with the pins of the MSP430F2001 processor.
P1.7/CAOUT/CA7/TDO/TDI
P1.6/TA1/CA6/TDI/TCLK
Also i dont know what TCLK does. i have made a MSP430 programmer and tried to interdace it with the MSP430F2001. This programmer i made according to http://msp430.webpark.pl and i can not seem to work. i am not sure about how to connect this unit to the MSP430F2001. Please help
I think that P1.7 and P1.6 are the JTAG TDI and TCLK pins. The data sheet should confirm it.

There are two kinds of JTAG for F2001.
The so called Spy-Bi-Wire JTAG connects to F2001 RST and TEST pins. (Plus Gnd and Vcc.)
The so called 4-wire JTAG connects to F2001 P1.4, P1.5, P1.6, and P1.7 pins. (Pluse RST, TEST, Gnd and Vcc.)
All I/O pins of F2001 have multiple functions. Read the DataSheet to see the default function and how to select the function you want.
