JTAG
There are 2 separate JTAG ports. One for the SoM and one for the SJA1110 on
the carrier.
6.13.1 JTAG for MPX-S32G274A (ST7)
The JTAG signals are available on a MIPI-10 header. This provides a direct
connection to the S32G274A processor on the SoM.
Note that when debugging the processor, the JCOMP signal needs to be pulled
high - meaning that SW2-4 must be ON.
