There is no additional action needed for using the
onboard MSP430 device for MDC/MDIO configuration. Connections are done at
bottom of the board and hence no jumpers should be placed on J14.
Note:
To use external MSP connection, please connect MDC of MSP to top-right most pin of J14 and MDIO to top-left most pin of J14.
