5.1.5 Power Settings
The voltage sources are selectable.
Jumper Setting Description
UVCC5 – SHDNSEL
Keep watching VCC5 of evaluation board S26
SHDNSEL
SHDNSE – UVCC3
Keep watching VCC3 of evaluation board
3.3V – VCCC3SEL
MB91V460’s VCC3 is supplied by evaluation board
S27
VCCC3SEL
VCCC3SEL – 3.5V
3.5V is supplied to VCC3 of MB91V460
UVCC3 – VCC5
Connect VCC3 of the adapter board to VCC3 of
evaluation board
S28
VCC5
VCC5 – UVCC5
Connect VCC5 of the adapter board to VCC5 of
evaluation board
UVCC5 – UVCC3H
VCC5H is generated from VCC5 by adding +1 V
S29
UVCC3H
UVCC3H – UVCC3
VCC5H is generated from VCC3 by adding +1 V
VCC3 – C
Connect to VCC3 of MB91V460
S8
C
C – VCC3C
Connect to the C terminal of the evaluation board
Default: S26 =
SHDNSEL–UVCC3 S27 = VCCC3SEL–3.5V
S28 = VCC5–UVCC5 S29 = UVCC3H–UVCC3
S8 = VCC3 – C
Note:
1) SHDNSEL: VCC3 or VCC5 can be supervised. If the selected voltage fails, the power
supply of the evaluation chip will be cancelled.
