Configuration Switch S1: General Purpose Functions (S1-1 to S1-8)

The eight General Purpose Input lines (GPI0-GPI7) on the MVME197LE may be configured with selectable switch segments S1-1 through S1-8. These switches can be read as a register (at $FFF40088) in the VMEchip2 LCSR. Refer to the VMEchip2 chapter in the MVME197LE, MVME197DP, and MVME197SP Single Board Computers Programmer’s Reference Guide for the status of lines GPI0 through GPI7. Factory configuration is with the general purposes input lines disabled (open).

Configuration Switch S1: System Controller Enable Function (S1-9)

The MVME197LE can be the system controller. The system controller function is enabled or disabled by configuring selectable switch segment S1-9. When the MVME197LE is the system controller, the SCON LED is turned ON. The VMEchip2 may be configured as a system controller as illustrated below. Factory configuration is with the system controller switch enabled (closed).
