IEGR is an 8-bit read/write register used to designate whether pins

IRQ

, and the internal

IRQ

signal used to interface to the FLEX™ decoder, are set to rising edge sensing or falling edge

sensing.

Bits 7 to 5: Reserved bits

Bits 7 to 5 are reserved: they are always read as 1 and cannot be modified.

Bit 4: IRQ

edge select (IEG4)

Bit 4 selects the input sensing of the

IRQ

pin and

ADTRG

pin.
