TriBoard Information

Other peripherals
For all other peripherals there are no special plugs on the board. The peripheral signals are available on the
different connectors. See
“Connector Pin Assignment” on Page 6-1
3.13
Toggle LED’s
The status LED’s are low active and can be controlled by Software.
Port 20 pin 11 up to pin 14 are connected to single LED’s (D306... D309) and powered by the normal
microcontroller voltage.
Port 20 pin 10 and Port 33 pin 5 up to pin 7 are connected to single LED’s (D302... D305) and powered by the
standby voltage. This means that this LED’s can be are activ also when the board is in standby mode and only the
standby voltage available (port 33 is powered by VEVRSB pin which is connected to standby supply of TLF35584).
In this case the port pins are controlled by the standby controller if available.
Note:
LED on P20.10 (D302) is always on if only VEVRSB is supplied.
3.14
Buttons
On the board are three buttons.
The reset button (S501) will apply a warm power on reset to the device.
The ENA button (S502) will be used to enable/wakeup the TLF35584.
The P33.9 button (S202) can be used by software as input. Also can this button used by the standby controller to
react on an event when only standby supply is available (e.g. wakeup the TLF35584 via P33.10).

Debug System
3.15.1
OCDS1
The OCDS1 signals are connected to the IDC16 plug (X401). They work with the port supply of Microcontroller (+5V
default or +3,3V). For pinout of the connector see
. You can connect any debugger to this connector.
The signals /BRKIN and /BRKOUT are not connected per default. If you need this signals in the connector then
assemble R424 and R425 or R426 with a 0R resistor.
If you connect a debug hardware make sure that the miniWiggler JDS (see
) is not
activ (ACTIV LED is off) and on the DAP connector (X402) is no hardware connected or the hardware is tristated.
If the ACTIV LED is on, then stop the active DAS Server ’UDAS’ and/or remove the USB connection to the PC.
If R214 up to R216 not assembled then the connector is not usable.
3.15.2
DAP
The board comes with a DAP connector (X402). For pinout of this connector see
. You can connect a DAP
hardware here. If you use this connector make sure that the miniWiggler JDS is not activ (ACTIV LED is off) and a
connected OCDS1 hardware is disconnected or tristated.
3.15.3
DAP_SCR
Additional DAP connector (X406) is connected to DAP_SCR. This DAP can be used as private DAP connection to
the standby controller. For pinout of this connector see
. You can connect a DAP hardware here. This
DAP use P33.6 and P33.7 which are connected to LED on the board. Maybe it is necessary to remove R393 and
R394 if the speed of the connection is not fast enough.
