You need to spend more time with the datasheet...
After about a minute I found these on page 3...
Using a format of a leading "1'' followed by the 35 data bits allows data transfer without an additional load signal. The 35 data bits are latched after the 36th bit is complete,
To blank the display at any time, (i.e., power on), clock in 36 or more zeroes, followed by a `one' (start bit), followed by 36 or more zeroes.
Figure 5 shows the Output Data Format for the MM5481. Because it uses only 14 of the possible 34 outputs, 20 of the bits are `Don't Cares'. Note that only alternate groups of 4 outputs are used.
