Jumpers Of The Evaluation Board Sk-91460-Main V1.2; Analogue Power Supply Voltage - Fujitsu MB91460 Getting Started

5.2 Jumpers of the evaluation board SK-91460-MAIN V1.2

In this section only the jumpers, influencing the adapter board are explained. Please refer to
the user guide of the evaluation board SK-91460-MAIN V1.2 for the other jumpers and
switches.

5.2.1 Analogue Power Supply Voltage

The power supply for the ports of the adapter board is generated by the evaluation board.
The voltage is selectable between 3.6 V and 5 V.
Jumper
SL260
SL262
ST370
ST371
Default: SL260 = open
ST370 = closed
By default, the I/O-ports are supplied by 5 V.
Note:
1) The Jumper S28 of the adapter board selects UVCC3 or MCU_VCC (UVCC5) as
power supply for the I/O-port. By default this Jumper selects MCU_VCC (UVCC5).
