The LED's, Hex switches and push-button switches are
connected to MCU pads vvia zero ohm links. If desired
these can be removed and direct connection made to the
LED or switch. All of the ports used for LED's /
Switches are also bonded out to the GPIO matrix
Hex Encoded Switch (Active High)
Switches are hard wired to 3.3V rather than 5V so it's not possible to drive 5V into a 3.3V pad (which would cause damage)
Similarly, the LED's are active low with 3.3v supply so can be safely coupled to pads on either 3.3V or 5V domains
The ADC input is limited to 3.3V, again to prevent driving 5V into a 3.3V pad which would cause damage

User Pushbutton Switches (Active High)
User Peripherals, Audio Controls and GPIO
LED's are SMD (1206) Yellow
User LED's (Active Low)
OMRON B3WN-6002 Pushbutton Switch
Since the Hex switch always
has an active output, the
jumper is to allow the switch
to be powered off
ADC Input Pot and Test Point
(Note - This is run from linear 3.3v regulator to
provide a stable input voltage)
(ADC1_P[0])
(0603 50V)
Note - PA1 is also the NMI pin!
Note that LED2 and LED4 (PG3
and PG5) can be controlled in
LPU_RUN mode (and also have pad
keepers in LPU_STANDBY)
