This register specifies the time in ADC sample periods (default 40μs) that must elapse following a zero-crossing
event before the MAXQ3181 declares a “no-zero crossing” fault. When this fault is declared, the NOZXF bit in the
X.FLAGS register is set.
This register specifies the duration of SPI timeout in ADC frames (default 320μs).
This register specifies the time in DSP cycles that the MAXQ3181 waits before accumulating energy. If this register is
nonzero, it is decremented on each DSP cycle. If the result of the decrement is nonzero, the results of the DSP cycle
are discarded and are not accumulated to the energy registers. This register is useful for delaying the initiation of
energy accumulation on startup or after some hardware function has been modified.
