Each device in the Z16FMC 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
(V
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 Z16FMC exits the POR state, the CPU fetches the Reset vector.
Following POR, the POR status bit in
is set to 1.
