SEGDIO51/OPT_TX pin to the LCD. If the second UART is
used, the jumper should be removed from the header.
32 J14 EMULATOR I/F
2x10 emulator connector port for the Signum ICE ADM-51
or for the TFP2 Flash Programmer.
33 JP54 E_RXTX
Three 2-pin headers that connects the E_RXTX, E_RXTX,
and E_TCLK pins to the LCD. The emulator pins should be
configured as LCD pins when this jumper is inserted.
34 JP8 SEGDIO55
2-pin header that allows connecting the
SEGDIO51/OPT_RX pin to the LCD. If the second UART is
used, the jumper should be removed from the header.

This connector is an isolated USB port for serial communi-
cation with the 71M6541.
38 U8 LCD
3-row LCD with 6 7-segment digits per row and special

40 JP5 UART_RX, ROUT
2-pin header for connection of the RX output of the isolated
USB port to the RX pin of the 71M6541. When the Demo
Board is communicating via the USB port, a jumper should
be installed on JP5. When the Demo Board is communi-
cating via the Debug Board plugged into J21, the jumper
should be removed.
