DESCRIPTION
J2 REFSEL Tie pin 03 These jumpers control the voltage levels of corresponding pins of the DUT.
• Short pin 01 = pulled high
• Short pin 02 = controlled by software through onboard microcontroller
(USB2ANY)
• Short pin 03 = pulled low
J3 HW_SW_CTRL Tie pin 03
J7 GPIO0/SYNCN Tie pin 01
J8 GPIO1/SCS Tie pin 02
J5 GPIO2/SOMI Tie pin 02
J10 VDD
Tie pins
1-2
This jumper decides whether the VDD pins are supplied by onboard LDO or
external power supply.
• Short pins 1-2: VDD is supplied by LDO.
• Short pins 2-3: VDD is supplied by VIN1 (external power supply).
J11 VDDO
Tie pins
1-2
This jumper decides whether the VDDO pins are supplied by onboard LDO or
external power supply.
• Short pins 1-2: VDDO is supplied by LDO.
• Short pins 2-3: VDDO is supplied by VIN2 (external power supply).
J12 VDDO level Tie pin 03
This switch controls the VDDO level when VDDO is supplied by LDO.
• Short pin 01: VDDO = 1.8 V.
• Short pin 02: VDDO = 2.5 V.
• Short pin 03: VDDO = 3.3 V.
J9 XO VCC Tie pin 01
This jumper powers up or down the onboard XO.
• Short pins 1-2: VCC of onboard XO is connected to LDO.
• Short pins 2-3: VCC of onboard XO is tied to ground.
J4 I2C/SPI
Tie pin
01,
pin 02
This jumper selects between I2C and SPI interface.
• To use I2C, short pin 01, pin 02 and leave other pins open.
• To use SPI, short pin 04, pin 05, pin 06, pin 07, and leave other pins open.
