Decode Enable Register (0x09)
The Decode Enable Register sets the decode mode. BCD/HEX decoding (either BCD code – characters 0:9, E, H, L,
P, and -, or HEX code – characters 0:9 and A:F) is selected by bit D2 (page 14) of the Feature Register. The Decode
Enable Register is used to select the decode mode or no-decode for each digit. Each bit in the Decode Enable Regis-
ter corresponds to its respective display digit (i.e., bit D0 corresponds to digit 0, bit D1 corresponds to digit 1 and so
on).
Note: A logic high enables decoding and a logic low bypasses the decoder altogether.
When decode mode is used, the decoder looks only at the lower-nibble (bits D3:D0) of the data in the Digit-Registers,
disregarding bits D6:D4. Bit D7 sets the decimal point (SEG DP) independent of the decoder and is positive logic (bit
D7 = 1 turns the decimal point on).
When no-decode mode is selected, data bits D7:D0 of the Digit-Registers correspond to the segment lines of the
AS1116.
