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 18) 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 Register corresponds to its respective display digit (i.e., bit D0 corresponds to digit 0,
bit D1 corresponds to digit 1 and so on). Table 9 lists some examples of the possible settings for the Decode Enable Register bits.
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). Table 9 lists the
code-B font; Table 10 lists the HEX font.
When no-decode mode is selected, data bits D7:D0 of the Digit-Registers correspond to the segment lines of the AS1115. Table 11 shows the
1:1 pairing of each data bit to the appropriate segment line.
