JP12 SVS_EN
closed = enable resets from system-voltage
supervisor chip.
As the SVS also monitors the reset-button,
this also disables manual reset if open.
Quite likely not to be changed.
2-pin small closed top N/O-9/10
JP13 CAN_RXD
closed = connect RXD on CAN-Interface to
MCU-port P2_41
2-pin small closed top J-4/5
JP14 CAN_TXD
closed = connect TXD on CAN-Interface to
MCU-port P2_40
2-pin small closed top I/J-4/5
JP15 UART_RXD
closed = connect RXD on UART-Interface
to MCU-port P0_45
2-pin small closed top O/P-6/7
JP16 UART_TXD
closed = connect TXD on UART-Interface
to MCU-port P0_47
2-pin small closed top O-6/7
R1 RTCKfb
closed = enable RTCK
open to avoid disturbance on TCK line if
RTCK is not used. If operating on lower
frequencies, can be left connected if no
problems arise with TCK.

On wide jumpers, the cap can be replaced by an ampere meter to measure current. However, care
must be taken to avoid inducing noise into the connected cables. Alternatively, if the cap is removed,
external power can be feed into the corresponding domain.
Caution: do not back-drive current into
the supply-rails. Check the schematics before connecting an external power-supply to a
jumper's output pin (the pin which drives the power-domain). Double-check before powering
up!
DVCC, AVCC5 and VDP5 (see further description below) must be set to the same voltage-rail
when zero point detection (ZPD) on any of the SMC ports is to be used. Check the datasheet
for further requirements on the combination of voltages.
When using external supplies, the allowed voltages specified in the datasheet must be
observed. This also applies to the ports driven by the domains.
4.2 Headers
Headers are intended to access interesting points on the PCB. They may have the same sizes as
regular jumpers.
Name Label Description Type Position
HDR1 5V0
5.0V rail voltage measuring header.
Do not inject any current here!
2-pin wide top D/E-2/3
HDR2 VIN_prot
Filtered and protected (against surges and reverse
polarity) input voltage. May be used to inject an
external supply.
2-pin wide top E-13
HDR3 3V3
3.3V rail voltage measuring header.
Do not inject any current here!
2-pin wide top D-6
HDR4, 5 GND
Access-points to the GND-plane. Can be used as
reference for scopes, logic-analyzers, voltmeters, etc. 3-pin wide

top B-14, O-11
HDR6 1V2
1.2V rail voltage measuring header.
Do not inject any current here!
2-pin wide top E/F-9
