The MPU will wait for the CE to signal that fresh data is ready (the XFER interrupt). It will read the data and perform additional
processing such as energy accumulation.

Fault, Reset, Power-Up
Reset Mode: When the RESETZ pin is pulled low or when V1 < VBIAS, all digital activity in the chip stops while analog circuits
are still active. The oscillator and RTC module continue to run. Additionally, all I/O RAM bits are cleared. As long as V1, the
input voltage at the power fault block, is greater than VBIAS, the internal 2.5V regulator will continue to provide power to the
digital section.
Once initiated, the reset mode will persist until the reset timer times out, signified by WAKE rising. This will occur in 4100
cycles of the real time clock after RESETZ goes high, at which time the MPU will begin executing its preboot and boot
sequences from address 00. See the security section for more description of preboot and boot.
