SJC / JTAG 

The i.MX7 can operate in two different JTAG modes. The pin JTAG_MOD defines the mode. 
The following table shows both modes as well as the mode set on the TQMa7x.

TAMPER 

The i.MX7 provides protection against unauthorised opening or manipulation of a device by tamper detection. 
Ten TAMPER pins are available for this purpose at the TQMa7x connectors. 
The following table shows the available signals:
