<WRAP center round important 60%>
In Revision 2.1 of the COM Express™ specification, the signals A98, A99, A101 and A102 have been
reclaimed from the VCC_12V pool. Therefore protection on the carrier board is necessary to avoid
damage to those when accidentally connected to 12 V. The implementation of this circuitry causes
lower transfer rates at both serial ports.

On the TQMxE40M the protection circuit is removed by default and the serial ports provide transfer
rates of up to 115 kbaud. Therefore the TQMxE40M can only be used in COM.0 Revision 2.1 and 3.0
Type10 pinout carrier boards. 
</WRAP>


===== CAN =====
The TQMxE40M provides a CAN interface. The signals for the CAN interface are shared with the serial port (SER1) signals and can
be configured via a register setting. 


===== DEBUG =====
The TQMxE40M includes a 14-pin flat cable connector, to connect an external debug module (TQ specific), to provide BIOS post
code information, debug LEDs and a JTAG interface for on-board FPGA.
This header is intended for TQ internal use only!
