9.4 8x8 LED Dot Matrix Driver
The application example in Figure 14 shows the AS1106 as an 8x8 LED dot matrix driver.
The LED columns have common cathodes and are connected to the DIG0:7 outputs. The rows are connected to the segment drivers. Each of
the 64 LEDs can be addressed separately. The columns are selected via the digits as listed in Table 7 on page 9.
The Decode Enable Register (see page 10) must be set to ‘00000000’ as described in Table 9 on page 10. Single LEDs in a column can be
addressed as described in Table 12 on page 11, where bit D0 corresponds to segment G and bit D7 corresponds to segment DP.
Note: For a multiple-digit dot matrix, multiple AS1106 devices must be cascaded.

9.5 Cascading Drivers
The example in Figure 14 drives 2 dot matrix digits using a 4-wire microprocessor interface. All Scan-Limit Registers should be set to the same
value so that one display will not appear brighter than the other.
For example, to display 12 digits, set both Scan-Limit Registers to display 6 digits so that both displays have a 1/6 duty cycle per digit. If 11 digits
are needed, set both Scan-Limit Registers to display 6 digits and leave one digit unconnected. Otherwise, if one driver is set to display 6 digits
and the other to display 5 digits one display will appear brighter because its duty cycle per digit will be 1/5 and the other display’s duty cycle will
be 1/6.
Note: Refer to No-Op Register (0xX0) on page 13 for additional information.
