Bit 3—VFBACKI Edge (VFEDG): Detects a rising edge on the VFBACKI pin.
Bit 2—Pre-Equalization Flag (PREQF): Detects the occurrence of an IHI signal 2fH
modification condition. The generation of a falling/rising edge in the IHI signal during a mask
interval is expressed as the occurrence of a 2fH modification condition. For details, see section
13.3.4, IHI Signal 2fH Modification.
Bit 1—IHI Signal Level (IHI): Indicates the current level of the IHI signal. Signal source and
phase inversion selection for the IHI signal depends on the contents of TCONRI. Read this bit to
determine whether the input signal is positive or negative, then maintain the IHI signal at positive
phase by modifying TCONRI.
