Motorola MVME6100 manual Flash Boot Bank Select Configuration Switch S4, Positio Function

Chapter 1 Hardware Preparation and Installation

S3 position 3-8 defines the VME Geographical Address if the MVME6100 is installed in a 3-row backplane. The following is the pinout:

Positio
n	Function
3	VMEGAP_L
4	VMEGA4_L
5	VMEGA3_L
6	VMEGA2_L
7	VMEGA1_L
8	VMEGA0_L

Setting the individual position to ON forces the corresponding signal to zero. If the board is installed in a 5-row backplane, the geographical address is defined by the backplane and positions 3-8 of S3 should be set to OFF. The default setting is OFF.
