Description

Display Control Register

Fields

MUX

Mux Configuration

0 (STATIC): Static

1 (DUPLEX): Duplex

2 (TRIPLEX): Triplex

3 (QUADRUPLEX): Quadruplex

5 (SEXTAPLEX): Sextaplex

7 (OCTAPLEX): Octaplex

WAVE

Waveform Selection

CONTRAST

Contrast Control

CHGRDST

Charge Redistribution Cycles

0 (DISABLE): Disable charge redistribution.

1 (ONE): Use 1 prescaled low frequency clock cycle for charge redistribution.

2 (TWO): Use 2 prescaled low frequency clock cycles for charge redistribution.

3 (THREE): Use 3 prescaled low frequency clock cycles for charge redistribution.

4 (FOUR): Use 4 prescaled low frequency clock cycles for charge redistribution.

BIAS

Bias Configuration

0 (STATIC): Static

1 (ONEHALF): 1/2 Bias

2 (ONETHIRD): 1/3 Bias

3 (ONEFOURTH): 1/4 Bias

MODE

Mode Setting

0 (NOEXTCAP): No External Cap. Uses an internal current source to generate VLCD. Use CONTRAST[4:0] to control VLCD.

1 (STEPDOWN): Use step down control with VLCD less than VDD. Use CONTRAST[5:0] to control VLCD level, and use SPEED to adjust VLCD drive strength.

2 (CPINTOSC): Charge pump used with internal oscillator. Use CONTRAST[5:0] to control VLCD level, and use SPEED to adjust oscillator frequency.
