8.5 Decode-Mode Register
In the AS1100 a BCD decoder is included. Every digit can be selected via register 09h to be decoded. The BCD code consists of the numbers 0-
9, E,H, L,P and -. In register 09h a logic high enables the decoder for the appropriate digit. In case that the decoder is bypassed (logic low) the
data Bits D7-D0 correspond to the segment lines of the AS1100. In Table 7 some possible settings for register 09h are shown. Bit D7, which
corresponds to the decimal point, is not affected by the settings of the decoder. Logic high means that the decimal point is displayed. In Table 8
the font of the Code B decoder is shown. In Table 9 the correspondence of the register to the appropriate segments of a 7 segment display is
8.6 Intensity Control and Interdigit Blanking
Brightness of the display can be controlled in an analog way by changing the external resistor (R SET ). The current, which flows between V DD
and ISET, defines the current that flows through the LEDs. The LED current is 100 times the ISET current. The minimum value of R SET should
be 9.53k ? , which corresponds to 40mA segment current. The brightness of the display can also be controlled digitally via register 0Ah. The
brightness can be programmed in 16 steps and is shown in Table 10 . An internal pulse width modulator controls the intensity of the display.
8.7 Scan-Limit Register
The scan limit register 0Bh selects the number of digits displayed. When all 8 digits are displayed the update frequency is typically 800Hz. If the
number of digits displayed is reduced, the update frequency is reduced as well. The frequency can be calculated using 8fOSC/N, where N is the
number of digits. Since the number of displayed digits influences the brightness, the resistor R SET should be adjusted accordingly. The Table 12
shows the maximum allowed current, when fewer than 4 digits are used. To avoid differences in brightness the scan limit register should not be
used to blank portions of the display (leading zeros).
