Low-Power, Active Energy, Polyphase AFE
The RAM-based registers contain both operating parameters and measurement results. They are divided into a num-
ber of categories that are described in the following sections.
This register contains bits that reflect the global status of the device.

Reserved.
When set, the high-frequency crystal has failed and the MAXQ3181 is operating from its internal ring
oscillator. Under these circumstances, energy accumulation is not accurate and the SPI bus does not
operate at full speed.
When set, the last reset was due to power-on-reset. Host should clear this bit to allow the next POR
detection.
When set, the last reset was caused by expired watchdog. The bit should be cleared (set to 0) by the
host to allow the next watchdog reset detection.
0 = The sequence of voltages presented to the voltage inputs is (-A-B-C-).
1 = The sequence of voltages presented to the voltage inputs is reversed (-A-C-B-).
This bit is meaningful only for connection systems that include all three voltages.
0 = The quantity being output on the CFP pin is positive (direct).
1 = The quantity being output on the CFP pin is negative (reverse).
