digit displays the no-decode hex value written to the
MAX6951 hardware.
Digit 0 (left side) through digit 7 (right side) display the
contents of the selected MAX6951 SRAM data plane,
P0 or P1.
All available functions except for changing a digit’s
value can be changed using the pulldown menu. Hot
keys (Alt + underlined letter) provide an alternative to
using the mouse to configure the MAX6951 EV kit.
Pressing on the Save Data button saves all the current
registers and SRAM (P0 and P1) data to the program’s
directory. Pressing on the Restore Data button
retrieves the saved register and SRAM (P0 and P1)
data and sends it to the MAX6951 EV kit hardware and

button clears SRAM Planes P0 and P1.
There are two methods for communicating with the
MAX6951 (Figure 2): through the Main Panel display or
through the general-purpose SPI utility. The utility config-
ures the SPI parameters such as clock polarity (CPOL),
clock phase (CPHA), and chip select (CS) polarity. The
fields where pin numbers are required apply to the pins
of the parallel port connector. When using the SPI utility,
the Main Panel display no longer keeps track of changes
sent to hardware. The SPI utility is preconfigured for the
proper setting of CPOL, CPHA, and CS.
The utility only handles the data in byte (8-bit) format.
Data that is longer than a byte must be handled as mul-
