Description
Invert bits 15 through 0. Each invert[x] bit corresponds to an irq[x] bit. When a given x
bit is 1, the corresponding serial IRQ input is assumed active low. Active low inputs are
inverted and presented internally as active high inputs.
Reserved. Write as 0.
Serial IRQ Enable. 0: Disable; 1: Enable
Serial IRQ Interface Mode. 0: Continuous (Idle); 1: Quiet (Active)
