Return to Mission Mode under Battery Power
Introduction
The 71M653x Family of metering ICs operates the MPU at reduced clock speed when in brownout mode, i.e. with
the mains power missing and with operation supported by a battery or super-capacitor. The reduced clock speed
supports basic operations like tamper detection, display and other household functions, but not communication at
UART speeds higher than 300 baud and computation-
