3.2.1 MCU Power Supply Voltage
JP21
With this jumper it is possible to connect the MCU external bus interface supply
VDD35 to 3.3 V. The MCU MB91460 series supports the function to supply the MCU
with 5V so that the normal I/O ports work with 5V and supply the external bus
interface with 3.3 V.
JP23
This jumper is used to connect the HVDD5 supply to MCUVcc. The HVDD5 is the
MCU supply voltage for the high current ports.
JP25
This jumper is used to connect the VDD5R MCU supply pins to MCUVcc.
JP26
This jumper is used to connect the Vcc voltage to MCUVcc.
JP27
This jumper is used to connect the VDD5 MCU supply pins to MCUVcc.
JP28
This jumper is used to connect the HVSS5 MCU pins to GND. HVSS5 are the GND
pins for the high current ports.

3.2.2 MCU Analogue Power Supply Voltage
The power supply as well as the reference voltage for the A/D-converter can be provided
internally or externally.
JP15
Connects power supply AVcc of the A/D converter to MCUVcc
JP16
Connects high reference voltage AVRH of the A/D converter to AVcc
JP18
Connects AVss of the A/D converter to GND
Note:
JP23, JP25, JP26, JP27 and JP28 can be used for
measurements of power consumption of the MCU.
