Each device in the ZNEO Z16F Series contains an internal POR circuit. The POR circuit
monitors the supply voltage and holds the device in the Reset state until the supply voltage
reaches a safe operating level. After the supply voltage exceeds the POR voltage threshold

this point, the system clock is enabled and the POR counter counts a total of 16 system
clock pulses. The device is held in the Reset state until the second POR counter sequence
has timed out. After the ZNEO Z16F Series exits the POR state, the ZNEO CPU fetches
the Reset vector. Following POR, the POR status bit in the

The ZNEO Z16F Series provides Low Voltage Brownout (VBO) protection. The VBO
circuit senses the supply voltage when it drops to an unsafe level (below the VBO
threshold voltage) and forces the device into the Reset state. While the supply voltage
