Figure 6-2. Key Components on the controlCARD - Back
WARNING
When the controlCARD is used in a high-voltage setup, it is the user’s responsibility to confirm that
the voltages and isolation requirements are identified and understood prior to energizing the board
or simulation. When energized, the controlCARD or components connected to the controlCARD
should not be touched. Furthermore, the capacitor C26:A should be removed to minimize the
possibility of leakage current flowing across the isolation barrier of the controlCARD.
Table 6-1. Hardware Connections
Connectors
J1:A
Emulation/UART connector - USB mini A connector used to provide XDS100v2 emulation and
USB-to-UART (SCI) communication through FTDI logic. S1:A determines which connections are
enabled to the MCU.
J1
FSI Header – Updated over previous designs. This header is now keyed, contains 2 data lines, and
has 3.3 V power.
LEDs
D2:A
Turns on when ISO JTAG logic is powered on (green)
D3:A
JTAG/UART RX toggle indicator (blue)
D4:A
JTAG/UART TX toggle indicator (blue)
D1
Controlled by GPIO–31 with negative logic (red)
D2
Controlled by GPIO–34 with negative logic (red)
D3
Turns on when the controlCARD is powered ON (green)
