2.1.1 EVM Jumpers

Table 2-1 lists the default jumper connections and functional description for the device configuration.

Table 2-1 Pinout & Onboard Jumpers
PIN NUMBER / NAME JUMPER CONNECTION DEFAULT CONNECTION DESCRIPTION
Pin1/PB1 J1 Closed(pin2, pin3) Jumper J1 configures the input for PB1. Connecting pin 2 and pin 3 is for devices with input active LOW configuration. Connecting pin 1 and pin 3 is for devices with input active HIGH.
Pin8/ KILL/PB2 J2 Closed(pin1, pin2) For TPS3423 devices, Jumper J2 configures the input for PB2. Connecting pin 2 and pin 3 is for devices with input active LOW configuration. Connecting pin 1 and pin 3 is for devices with input active HIGH. For TPS3424 devices, Jumper J2 can be left floating.
Pin4/SPT/INT2 J3 Closed(pin3, pin4) For TPS3423 devices, Jumper J3 connects pin 4 to a 10kΩ pull-up to VDD and the pin can be probed from TP3. For TPS3424 devices, Jumper J3 is to configure the short press timing with various capacitors available on the board.
Pin5/LPT/INT1 J4 Closed(pin2, pin3) For TPS3423 devices, Jumper J4 connects pin 4 to a 10kΩ pull-up to VDD and the pin can be probed from TP4. For TPS3424 devices, Jumper J4 is to configure the long press timing with various capacitors available on the board.
Pin6/OUT1/OUT1 J7 Open(pin1) Jumper J7 connects RESET/RESET to a 10kΩ pull-up for devices with open-drain outputs. For push-pull output devices, set this jumper to floating.
Pin7/INT/OUT2/OUT2 J8 Closed(pin1, pin2) For TPS3423 Jumper J8 connects RESET2/RESET2 to a 10kΩ pull-up for devices with open-drain outputs. For push-pull output devices, set this jumper to floating. For TPS3424 J8 connects INT to a 10kΩ pull-up.
Pin6/OUT1/OUT1 J5 Open(pin1) Jumper J5 connects R3 pull-up resistor to VDD. If pull-up voltage for RESET/RESET is not VDD, leave J5 floating and input desired pull-up voltage to TP5
Pin7/INT/OUT2/OUT2 J6 Closed(pin1, pin2) Jumper J6 connects R4 pull-up resistor to VDD. If pull-up voltage for RESET/RESET for TPS3423 or INT for TPS3424 is not VDD, leave J6 floating and input desired pull-up voltage to TP6
Pin8/KILL/PB2 J9 Closed(pin1, pin2) Important Jumper J9 is floating for TPS3423 devices. For TPS3424, J9 configures the KILL functionality. For KILL enabled connect pin 1 and pin 2, connecting Pin 9 to VDD. For KILL disabled, connect pin 2 and pin 3, connecting pin 9 to GND
