ADP_EN Bit D4

This bit enables the ADP function. ADP is enabled when

this bit is a logic one. ADP is disabled when this bit is a

logic zero.

OLE_EN2 through OLE_EN0 Bits [D3:D1]

These bits enable Other Lighting Effects (OLE), including

the auto-dim full and auto-dim partial, as shown in Table

25. Auto-dim functions are described in detail in the

Applications Information section.

Reserved (no effects)

Auto-dim full (group #1)

Auto-dim partial (group #1)

Reserved (no effects)

PWM_BYP Bit D0

When this bit is a logic zero, the PWM pin functions nor-

mally. When this bit is a logic one, the PWM pin is disabled,

so that a high or low on the PWM pin has no effect.
