Part identifier Jumper type Description Reference section
JP13 (DNP) 1x2 pin header
JP40 (DNP) 1x2 pin header
VOUT_SYS / VDD_SYS supply enable jumpers.
JP13 and JP40 are not populated on the board.
If populated, either can be used to enable
VOUT_SYS / VDD_SYS supply. JP13 uses the
P1V8_EXT supply as input whereas JP40 uses
the VDD_DCDC supply as input.
JS1 (DNP) 1x2 pin header VDD_MEM supply enable jumper. JS1 is not
populated but pin 1 and pin 2 positions of the
jumper are connected through a physical (trace)
connection on the secondary (bottom) side of
the PCB. Therefore, the VDD_MEM supply is
enabled, by default.
When populated, JS1 can be used to enable/
disable the VDD_MEM supply. If populating
the jumper to allow manual connection/
disconnection, cut the trace connection between
its pin 1 and pin 2 positions.
JS2 (DNP) 1x2 pin header P_LED supply enable jumper. JS2 is not
populated but pin 1 and pin 2 positions of the
jumper are connected through a physical (trace)
connection on the secondary (bottom) side
of the PCB. Therefore, the P_LED supply is
enabled, by default.
When populated, JS2 can be used to enable/
disable the P_LED supply. If populating
the jumper to allow manual connection/
disconnection, cut the trace connection between
its pin 1 and pin 2 positions.
JP16 1x3 pin header LPUART controller selection jumper for
receiving UART signal from MCU-Link:
• 1-2 shorted (default setting): LPUART1
controller of the target MCU receives UART
signal from MCU-Link
• 2-3 shorted: LPUART0 controller of the target
MCU receives UART signal from MCU-Link
JP17 1x3 pin header LPUART controller selection jumper for sending
UART signal to MCU-Link:
• 1-2 shorted (default setting): LPUART1
controller of the target MCU sends UART
signal to MCU-Link
• 2-3 shorted: LPUART0 controller of the target
MCU sends UART signal to MCU-Link
JP19 1x3 pin header LIN_RX signal direction control jumper:
• 1-2 shorted (default setting): LIN_RX signal
direction is from J11 (pin 1) to the target MCU
(pin PTA16/PTC2)
• 2-3 shorted: LIN_RX signal direction is from
the target MCU (pin PTA16/PTC2) to J11 (pin
1)
JP21 1x2 pin header USB-to-UART bridge disable jumper:
