TDA2: How many EMU lines of JTAG port are necessary to be connected to access all the processors?

Part Number:TDA2

Due to space-constraint, I am trying to minimize the JTAG connector size. However, I have some doubts on questions below:

1. Is it enough to connect only JTAG and EMU[1:0] to TDA2SG to access all the processors using 14-pins connections?

2. What will be left non-accessible without EMU[4:2]?

3. Is nSRST a must-have connection?
