Direct PWM Control Bits vs. PWM Duty Cycle 17 D2 PWM to 1E D9 PWM • PWM duty cycle control for outputs D2 to D9. The control registers and control bits for D2 output to D9 output are similar to that given to D1. 26 D1 CURRENT CONTROL • D1 LED driver output current control register. The resolution is 8-bits and step size is 100 μA. . CURRENT bits Output Current (typ.) 00000000 0.0 mA 00000001 0.1 mA 00000010 0.2 mA ... ... 10101111 17.5 mA default setting .... .... 11111110 25.4 mA 11111111 25.5 mA 27 D2 CURRENT CONTROL to 2E D9 CURRENT CONTROL • The control registers and control bits for D2 output up to D9 output are similar to that given to D1 output. 36 MISC • This register contains miscellaneous control bits. • 36 — Bit [7] VARIABLE_D_SEL • Variable D source selection. • 1 = variable D source is the LED test ADC output (LED TEST ADC). This allows, for example, program execution control with analog signal. • 0 = variable D source is the register 3C (VARIABLE). • 36 — Bit [6] EN_AUTO_INCR • The automatic increment feature of the serial bus address enables a quick memory write of successive registers within one transmission. • 1 = serial bus address automatic increment is enabled. • 0 = serial bus address automatic increment is disabled. • 36 — Bit [5] POWERSAVE_EN • 1 = power save mode is enabled. • 0 = power save mode is disabled. See section “Automatic Power Save Mode” for further details. • 36 — Bits [4:3] CP_MODE • Charge pump operation mode. • 00 = OFF.
