LPCXpresso55S36 Development Board User Manual
Part identifier Jumper type Description Reference section
JP7 1x2 pin header MCU-Link debug probe target selection jumper:
• Open (default setting): The MCU-Link debug
probe or an external debug probe can be
connected to the onboard target MCU. Use
this setting when the target MCU operates in
Normal mode (its debug interface is enabled).
• Shorted: The MCU-Link debug probe can be
connected to an external target MCU. Use
this setting when using the MCU-Link debug
probe for debugging an external target MCU.
JP8 1x3 pin header Target power selection jumper:
• Pins 1-2 shorted (default setting): Onboard
target MCU is used as debug target or an
external target MCU is used as debug target
but it uses board power
• Pins 2-3 shorted: An external target MCU
is used as debug target and it uses its own
power
Section 3.4
JP33 1x2 pin header MCU_VCC_3V3_1V9 supply enable jumper:
• Open: MCU_VCC_3V3_1V9 supply is OFF
• Shorted (default setting):
MCU_VCC_3V3_1V9 supply is available
JP20 1x2 pin header MCU_VDD supply enable jumper:
• Open: MCU_VDD supply is OFF
• Shorted (default setting): MCU_VDD supply is
available
JP21 1x2 pin header Target MCU VDDA power enable jumper:
• Open: MCU_VDDA power supply is OFF
• Shorted (default setting): MCU_VDDA power
supply is available
JP22 1x2 pin header MCU_VBAT supply enable jumper:
• Open: MCU_VBAT supply is OFF
• Shorted (default setting): MCU_VBAT supply
is available
JP28 1x2 pin header MCU_MAIN supply enable jumper:
• Open: MCU_MAIN supply is OFF
• Shorted (default setting): MCU_MAIN supply
is available
JP74 1x2 pin header
JP75 1x2 pin header
These two jumpers are used together to
connect a power supply to the current
measurement circuit for measuring its current.
By default, both are shorted.
Section 3.8
J20 (DNP) 1x2 pin header Target MCU external VBAT power enable
jumper. J20 is not populated on the board.
If populated, it can be used to supply VBAT
power to the target MCU from an external power
source.
