detects the low supply voltage and initiates the RESET via the Reset controller. The
eZ80F92 device remains in RESET mode until the supply voltage again returns above the
POR voltage threshold (V
nal. The VBO circuitry rejects very short negative brown-out pulses to prevent spurious
RESET events. VBO operation is illustrated in Figure 4. The signals in this figure are not
