8x8 Dot Matrix Mode
The application example in Figure 21 shows the AS1116 in the 8x8 LED dot matrix mode.
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 11 .
The Decode Enable Register ( see page 12 ) must be set to ‘00000000’ as described in Table 9 on page 12 . Single LEDs in a column can
be addressed as described in Table 12 on page 13 , where bit D0 corresponds to segment G and bit D7 corresponds to segment DP.
Note: For a multiple-digit dot matrix, multiple AS1116 devices can be cascaded easily.

Supply Bypassing and Wiring
In order to achieve optimal performance the AS1116 should be placed very close to the LED display to minimize effects of electromagnetic inter-
ference and wiring inductance.
Furthermore, it is recommended to connect a 10 F electrolytic and a 0.1 F ceramic capacitor between pins V DD and GND to avoid power sup-
