Programming

This section presents reference information to help you understand the

XVME-956/101 unit programming interface.  It also provides information on

control register functions and how to read the registers for power alarm, and

battery voltage monitoring.  Data is also included on selecting pages within

large memory devices, board number, window address, and Flash EPROM

programming.

Control Register Usage

The control registers are I/O mapped, 8-bit registers that enable certain

functions and provide information about others.  These functions are dis-

cussed in detail in the sections following.
In systems with multiple XVME-956/101 modules, all modules at the same

I/O port address receive the same information in their control registers.

However, because Board Number is decoded from the contents of Control

Register 1, only one module per address is selected.  At 

power up

 and

CTRL-ALT-DEL reset

, the control registers are reset to all zeros by the

BIOS.

Control Register 1 Functions

The contents of Control Register 1 selects a particular XVME-956/101 mod-

ule by board number, selects a particular socket on that module, and selects

"pages" of large devices in that socket.
To select a particular socket, write the lower 3 bits of control register with

the desired socket number (in binary).  The binary addresses of the sockets

are given in Table 4-18.
