4 Configuration and Test-Points
4.1 Jumpers
The SK-MB9EF120-002,-003 provides multiple options to access signals and configure its properties.
For this, it has two variants of jumpers:
(regular) Jumpers consist of two or three pin-headers and a small cap. They can be changed
without extra tools. They are used where changes are likely to occur. Wide jumpers use a 2.54mm
raster, while small jumpers use 2.00mm . The former are used for power-connections where also
measuring may be required, while the latter are sole configuration jumpers.
solder-jumpers change more basic options, the vast majority of applications do not require
changing them from their defaults. A solder-jumper is either a single 0R0 resistor or two resistors of
which only one may be placed. For the latter, a shared pad is often used to avoid placing both
resistors accidentally.
Name Label Description Type Default Position
JP3 AVDD5
select ADC-supply:
1-2 = AVRH5
2-3 = VDP5
open = external
Caution: the ADC is an analog subsystem
and therefore sensitive to noise induced
from the power-supply lines.
3-pin wide 2-3 top N-8
JP2 AVRH5
open = access ADC VRH5 (reference
input).
Caution: the ADC is an analog subsystem
and therefore sensitive to noise induced
from the power-supply lines.
2-pin wide closed top N-7/8
JP1 AVSS5
open = access ADC VSS.
Caution: the APIX is an analog subsystem
and therefore sensitive to noise induced
from the power-supply lines.
2-pin wide closed top N-8
JP10 VDP5
select VDP5 supply-rail:
1-2 = 3V3 (3.3V on-board rail)
2-3 = 5V0 (5.0V on-board rail)
open = external
3-pin wide 2-3 top E/F-5/6
JP8 DVCC
select DVCC supply-rail:
1-2 = 3V3 (3.3V on-board rail)
2-3 = 5V0 (5.0V on-board rail)
open = external
3-pin wide 2-3 top F-5/6
JP6 MCU_VDD open = access 1.2V supply for MCU. 2-pin wide closed top E-9
JP7 MCU_VDP3 open = access VDP3 domain for MCU . 2-pin wide closed top M-9/10
JP11 MCU_VDP5 open = access VDP5 domain for MCU. 2-pin wide closed top G-5/6
JP9 MCU_DVCC open = access DVCC domain for MCU. 2-pin wide closed top G-5/6
JP4 RTCK-sel
enable/disable RTCK on JTAG:
1-2 = disable (pulled to GND)
2-3 = enable
open =
invalid
see also solder-jumper R7
3-pin small 1-2 top G/H-15
JP5 TRC_RST
closed = enable resets from debug and
trace connector.
Quite likely not to be changed.
2-pin small closed top G/H-14/15
