The no-op register is used when the MAX6950/
MAX6951 are connected as the last device on a chain
of cascaded SPI devices. To write the other cascaded
device(s), ensure that while the intended device
receives its specific command, the MAX6950/MAX6951
receive a no-op command.

The display-test register switches the drivers between
one of two modes: normal and display test. Display-test
mode turns all LEDs on by overriding, but not altering,
all control and digit registers (including the Shutdown
register) In display-test mode, eight digits are scanned
and the duty cycle is 7/16 (half power). Table 11 lists
the display-test register format.
