TDA2HV: minimum pins for JTAG connection to debug TDA2HV

Part Number: TDA2HV

Hello,

The custom board uses Compact TI 20-Pin.

Could you please let me know what is minimum JTAG pins to debug TDA2HV?

As I understand it, a typical JTAG interface requires only 4 pins: TMS, TDI, TDO, and TCK to be used.

Do EMU0/1/2/3/4 need to be connected to JTAG emulator?

What is the restriction without EMU0/1/2/3/4 connection to JTAG emulator?

Thanks and Best Regards,
