Jumper Label Description
Position
J2 1-2 LDO 3.3V LDO 3.3V. Install for complete EVM operation. Remove to allow power access to
only the sequencer device.
J25 1-2 SCL EEPROM SCL. For EVM manufacturing only.
J26 1-2 SDA EEPROM SDA. For EVM manufacturing only.
J9 1-2 GPI1 General purpose input #1. Install shunt to allow status LED operation.
J14 1-2 GPI2 General purpose input #2. Install shunt to allow status LED operation.
J19 1-2 GPI3 General purpose input #3. Install shunt to allow status LED operation.
J22 1-2 GPI4 General purpose input #4. Install shunt to allow status LED operation.
J13 1-2,7-8 PM ADDR PMBus address (default to 101). Remove shunts for JTAG operation at address 126.
J7 TCK JTAG TCK. Install shunt when JTAG operation is desired.
J3 TDI JTAG TDI. Install shunt when JTAG operation is desired.
J8 TDO JTAG TDO. Install shunt when JTAG operation is desired.
J4 TMS JTAG TMS. Install shunt when JTAG operation is desired.
J27 1-2 LEDEN Status LED enable. Install to enable non-PWM GPIO status LED’s. Remove to
disable status LED loading on the GPIOs.
J28 1-2, 3-4, 5-6, 7-8, LEDEN Status LED enable for FPWMs (GPIO5-GPIO12). Install to enable FPWM GPIO
9-10, 11-12, status LED’s. Remove to disable status LED loading on the FPWM GPIOs.
13-14, 15-16
J15 GPIO14/TX Debug port TX (used for debug)
J16 GPIO15/RX Debug port RX (not used during debug)
