4.4.4 On-Board LEDs
The S5D9 MCU board provides 3 on-board LEDs for user-defined functions. A fourth LED is used to indicate 3.3V
power presence. The LEDs are connected to general purpose output pins through a single resistor. The output active
state is 1. The table below describes the mapping between the LEDs and the ports that drive them.

4.4.5 USB Device
This USB Micro-B connection jack connects the S5D9 MCU to an external USB 2.0 Host,
Full Speed capable. The USB power presence (VBUS) is wired to GPIO input P4_7 after it
is passed through resistor divider.
