JUMPER DESCRIPTION:
SMD jumper description
The power supply for SAM9-L9260 must be regulated +5VDC. Please apply
exactly 5V as the same power line goes to USB hosts and if you apply over 5V
you will damage your USB devices attached to the host.
The current consumption is typical 250mA with 180 MHz clock of SAM9260
and 90MHz clock of external bus.
For the RTC there is a battery backup power supply from a small 3V Li
battery type CR2032.
SAM9-L9260 reset circuit is made with a 4.7k pull-up resistor and a RST
button connected to GND.
Quartz crystal Q1-18.432Mhz is connected to SAM9-L9260 Xin and Xout
pins.
Quartz crystal Q2-32768Hz is connected to SAM9-L9260 Xin32 and Xout32
pins.
3.3V_MCU_E Enable 3.3V to the SAM9260 microcontroler.
1.8V_MCU_E Enable 1.8V to the SAM9260 microcontroler.
BDS_E
TCK-RTCK Connects RTCK and TCK pins of SAM9260.
WPE
3.3V_E
Enable the main 3.3V regulator VR1(3.3V)-RC1587

BounDary Scan Enable. The BDS_E jumper is used to select
the JTAG boundary scan when JTAGSEL pin asserted at a
high level (tied to VDDBU). This pin integrates a permanent
pull-down resistor of about 15KΩ to GNDBU. When BDS_E is
open JTAG function is selected.
Default state – open
Default state open
Connects PC4(pin62) to Write Protection pin of SD/MMC
socket. If WP function is not used, WPE jumper has to be open
and PC4 is available of EXT connector pin 20.
Default state - closed
