PROSLIC^ WINDOWS^ GUI SOFTWARE USER’S GUIDE
1. Introduction
The ProSLIC^ Windows^ (graphical user interface) GUI
software uses the parallel port of a PC to communicate
with the ProSLIC’s SPI port. This document applies to
Rev 1.85 of the software. The program runs on
Windows® 98/NT/2000. Invoking the ProSLIC Windows
GUI software causes the device initialization sequence
to take place. During device initialization, all the direct
registers are read and put into the direct register table.
Default values are written to the indirect registers and
are read back into the indirect table. The device
number, revision number and clock frequency are
shown on the top left of the screen. (See Figure 1.)

The Reset button pulls the ProSLIC reset pin to low
causing a hardware reset.
The Reinitialize button repeats the device initialize
sequence.
The Reg Set button carries out the register writes
shown in Table 1.

When the Continuous Read All button is in the “on”
position, the direct register table is continuously
updated. The registers are updated until the Continuous
Read All button is changed to the “off” position.
When the Read All Indirect button is pressed, the values
in the indirect register table are updated
instantaneously. Continuous read is not available for the
indirect registers.
