LPCXpresso55S36 Development Board User Manual
Part identifier Jumper type Description Reference section
JP79 1x3 pin header Target MCU pin PIO0_28 signal selection
jumper:
• Pins 1-2 shorted (default setting): Target MCU
pin PIO0_28 communicates through FC0
SCK / I3C0 pull-up resistor control / USB0
overcurrent signal
• Pins 2-3 shorted: Target MCU pin PIO0_28
communicates to debug trace connector (J38)
through TRACE_D3 signal
JP80 1x3 pin header Target MCU pin PIO0_30 signal selection
jumper:
• Pins 1-2 shorted (default setting): Target MCU
pin PIO0_30 communicates to MCU-Link /
USART connector JP3 through FC0 RXD
signal
• Pins 2-3 shorted: Target MCU pin PIO0_30
communicates to debug trace connector (J38)
through TRACE_D1 signal

1.9 Push buttons
The LPCXpresso55S36 push buttons are shown in Figure 2 and are described in the
table below.
Part identifier Switch name Description
SW1 Wake-up button (WK_TMP) Wakes up the target MCU (LPC5536) from Deep Power-
Down mode. It connects to the target MCU pin PIO1_18.
SW2 Reset button (RESET) Causes the target MCU and board peripherals to reset to
their default states and executes the boot code. If the target
MCU is in Deep Power-Down mode, it comes out of this
mode. SW2 connects to the target MCU pin RESETN.
SW3 User button (USR) The purpose of this button can be defined in user application
code. It connects to the target MCU pin PIO0_17.

1.10 LEDs
The table below describes the LPCXpresso55S36 light-emitting diodes (LEDs) that
correspond to the target MCU. The board also has some MCU-Link specific LEDs, which
are described in Section 3.9.
Part identifier LED color LED name Description
D4 Red/green/blue RGB User application LED. It is connected to the VCC_3V3
supply. This LED can be controlled through a user
application.
D5 Red PWR Indicates system power-on status. It is connected to
the VCC_3V3 supply. When the board is powered up,
this LED turns ON.
