Table 6. LPC55S36-EVK jumpers (continued)
Part identifier
Jumper type
Description
Reference section
• Shorted (default setting): VCC_3V3_1V9
supply is available in MCU-Link current
measurement circuit
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.
J43
2x2 pin header
Target MCU boot configuration jumper. Pins 1-2
of J43 connect to PIO0_5 pin (ISP0) of the target
MCU. Pins 3-4 of J43 connect to PIO0_7 pin
(ISP1) of the target MCU. Pins 1-2 and pins 3-4
of J43 together determine the boot source for the
target MCU.
• Pins 1-2 and pins 3-4 open (default
settings): Both ISP0 and ISP1 are High.
Target MCU (LPC5536) follows normal boot
sequence.
• Pins 1-2 open and pins 3-4 shorted: ISP0 is
High and ISP1 is Low. Target MCU boots in
In-System Programming (ISP) mode.
JP27
1x2 pin header
MCU-Link serial wire debug (SWD) disable
jumper:
• Open (default setting): MCU-Link SWD
feature is enabled. MCU-Link drives SWD of
target MCU or external target MCU.
• Shorted: MCU-Link SWD feature is disabled.
This setting of JP27 can be used when
connecting an external debug probe for
debugging the target MCU. This setting
of JP27 is also recommended when using
shared I3C signals.
JP46
1x3 pin header
Target MCU pin PIO1_31 input selection jumper:
• Pins 1-2 shorted: Target MCU monitors
USB0 VBUS power
• Pins 2-3 shorted (default setting): Target
MCU receives input from jumper JP53
JP53
1x3 pin header
Jumper JP46 pin 3 I/O selection jumper:
• Pins 1-2 shorted: Jumper JP46 pin 3 sends/
receives clock I/O to/from audio codec /
audio expansion connector
