Description

N/A

Reserved.

INT_CFG

Interrupt configuration.

1 = processor interrupt deasserts for 50 μs and reasserts with pending events.

0 = processor interrupt remains asserted if the host tries to clear the interrupt while there is a pending event.

nSTBY

1 = device is in active mode.

0 = device is in standby mode, only the I2C interface is enabled.

DIM_EN

DIM_EN is set by the hardware after a DIM timeout. The user may also force the backlight into DIM mode by

asserting this bit. DIM mode can only be entered if BL_EN is also enabled.

1 = backlight is operating at the DIM current level (BL_EN must also be asserted).

0 = backlight is not in DIM mode.

N/A

Reserved.

SIS_EN

Synchronous independent sinks enable.

1 = enables all LED current sinks designated as independent sinks. All of the ISC enable bits must be cleared; if

any of the SC_EN bits in Register 0x10 are set, this bit has no effect.

0 = disables all sinks designated as independent sinks. All of the ISC enable bits must be cleared; if any of the

SC_EN bits are set in Register 0x10, this bit has no effect.

CMP_AUTOEN

1 = backlight automatically responds to the comparator outputs (L2_OUT and L3_OUT). L2_EN and/or L3_EN

must be set for this to function. BLV values in Register 0x04 are overridden.

0 = backlight does not autorespond to comparator level changes. The user can manually select backlight

operating levels using Bit BLV in Register 0x04.

BL_EN

1 = backlight is enabled (nSTBY must also be asserted).

0 = backlight is disabled.
