Low-Power, Multifunction, Polyphase AFE
with Harmonics and Tamper Detect
On every DSP cycle, the contents of the X.REA register are tested, and, if negative, absolute values are added to
this register. When this register overflows, the RNOV bit in the X.EOVER register is set.
On every DSP cycle, the contents of the X.APP register are added to this register. When this register overflows, the
SOV bit in the X.EOVER register is set.
