i.MX8M - Entering Boundary Scan mode

i´m working on the test of the i.MX8M and have a question to the processor´s bsdl file:


Before it mentions the "attribute compliance pattern" it says:
"It lists a set of design ports and the values that they should be set to, in order to enable compliance to IEEE Std 1149.1"


How strict is the part "should be set to" meant?
And which pins are absolutely necessary to achieve JTAG mode?


Thanks for your help!
