Configuration Switches
The location of the switches, connectors, and LED indicators on the
MVME197LE is illustrated in Figure 2-1. The MVME197LE has been factory
tested and is shipped with factory switch settings that are described in the
following sections. The MVME197LE operates with its required and factoryinstalled Debug Monitor, MVME197Bug (197Bug), with these factory switch
setting.
Configuration Switch S1: General Information
Switch S1 is a bank of nine two-way switch segments. The following
illustration shows the factory configuration of switch S1. The bit values are
read as a one when the switch is OFF (open), and as a zero when the switch is
ON (closed). The default value for switch S1 is shown below.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).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).Serial port 4 can be configured to use clock signals provided by the RTXC4 and
TRXC4 signal lines. Switch segments S6-1 and S6-2 on the MVME197LE
configures serial port 4 to drive or receive TRXC4 and RTXC4, respectively.
Factory configuration is with serial port 4 set to receive both signals (open).
The remaining configuration of the clock lines is accomplished by using the
Serial Port 4 Clock Configuration Select header on the MVME712M transition
module. Refer to the MVME712M Transition Module and P2 Adapter Board
User’s Manual for configuration of that header.
