Emulation/UART connector - USB mini A connector used to provide
xds100v2 emulation and USB-to-UART(SCI) communication through
FTDI logic. A:SW1 determines which connections are enabled to the
MCU.
SD Micro card slot – connects to MCU via SPI
USB connector – USB micro AB connector supports USB 2.0 host/device
USB PHY connection enable/disable jumpers –

All jumpers up
the controlCARD via GPIOs 42, 43, 46, 47, 120, and 121.

All jumpers down – The MCU will not connect to the USB PHY
and all signals will instead go through the 180pin controlCARD
connector.
Turns on when the controlCARD is powered ON (green)
Controlled by GPIO-31 with negative logic (red)
Controlled by GPIO-34 with negative logic (red)
Turns on when ISO JTAG logic is powered on (green)
JTAG/UART RX toggle indicator (blue)
JTAG/UART TX toggle indicator (blue)
Alternate Reference Configuration Resistors:
These resistors allow the user to choose whether the alternate reference
for the ADCs will be given by:

If R42 is populated & R43 is unpopulated -
A precision 3.0V reference

If R42 is unpopulated & R43 is populated -
The reference will be given by pin 45 of the HSEC controlCARD
connector. This will presumably allow the baseboard to provide
the desired voltage reference.
Optional RC input filter for all ADC inputs
– The MCU will be connected to the USB PHY on
