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.

Configuration and Test-Points

Description

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.

open = access ADC VRH5 (reference

input).

Caution: the ADC is an analog subsystem

and therefore sensitive to noise induced

from the power-supply lines.

open = access ADC VSS.

Caution: the APIX is an analog subsystem

and therefore sensitive to noise induced

from the power-supply lines.

select VDP5 supply-rail:

1-2 = 3V3 (3.3V on-board rail)

2-3 = 5V0 (5.0V on-board rail)

open = external

select DVCC supply-rail:

1-2 = 3V3 (3.3V on-board rail)

2-3 = 5V0 (5.0V on-board rail)

open = external

open = access 1.2V supply for MCU.

open = access VDP3 domain for MCU.

open = access VDP5 domain for MCU.

open = access DVCC domain for MCU.

enable/disable RTCK on JTAG:

1-2 = disable (pulled to GND)

2-3 = enable

open = invalid
