2.4.7 JP8, CANB Termination Resistor Select
2.5 LEDs
Jumper JP8 is used to select the termination resistor on the CANB interface. When
installed a termination resistor is placed between pins 3 and 4 of the connector J11.
This jumper is installed at the factory. The positions are shown in the table below.
The layout of this jumper is shown in the figure below.
The eZdsp
+5 volts and is normally ‘on’ when power is applied to the board. LED DS2 is under
control of the GPIO32 line from the processor. DS201 is connected to the embedded
USB emulator and shows the status of the emulation link. These are shown in the table
below.
