Frame Time Register (0x02)
Every single frame in a movie is displayed for a certain time before the next frame is displayed. This time can be set within this register with 4
bits. The stated values in Table 18 are typical values. Per default this register is set to 0x00.

Display Option Register (0x03)
With the scan-limit it can be controlled how many digits are displayed in each matrix. When all 18 digits in the 2 matrix configuration are dis-
played, the display scan rate is 430Hz (typ.). If the number of digits to display is reduced, the update frequency is increased. Per default this reg-
ister is set to 0x07.
