The following sections contain a functional description of the major blocks on
the MVME197LE single board computer.
Front Panel Switches and Indicators
There are two push-button switches and six LEDs on the front panel of the
MVME197LE module. The switches are RESET and ABORT. The RESET
switch (S3) will reset all onboard devices and drive the SYSRESET* signal if the
board is the system controller. The RESET switch (S3) will reset all onboard
devices except the DCAM and ECDM if the board is not the system controller.
The VMEchip2 generates the SYSREST* signal. The BusSwitch combines the
local reset and the reset switch to generate a local board reset. Refer to the Reset
Driver section in the VMEchip2 chapter of the MVME197LE, MVME197DP, and
MVME197SP Single Board Computers Programmer’s Reference Guide for more
