Jumpers, Buttons and LEDs
PLL jumper
Leave this jumper open if you want the
onboard the NB1000 to run at full
speed (88.4736MHz). Close the jumper if you want the EM1000 to run at 1/8th the
full speed (11.0592MHz). Notice, that the jumper state is only recognized after the
power-up or external reset (caused by pressing the reset button). The PLL mode
can also be changed programmatically. For more information see
Control, and Mode Selection Lines
topic of the EM1000 documentation.
MD jumper and mode button
The function of the mode button is described in
. On the
NB1000 board, MD jumper is connected in parallel with the button.
US jumper
This jumper selects the serial port of the
that will be used for firmware
upgrades. When the jumper is opened, serial port 1 is used (TX0 (#17) and RX0
(#19) lines on the
serial port 1, thus making serial firmware upgrades possible.
When the US jumper is closed, debug serial port is used.
Reset button
This button is connected to the RST pin of the
. Pressing this button causes
an "external" reset.
