Figure 3. Power-On Reset Operation
Voltage Brownout Reset
If, after program execution begins, the supply voltage (V
) drops below the Voltage
CC
Brownout threshold (V
), the eZ80F92 device resets. The VBO protection circuitry
VBO
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
) and the Reset controller releases the internal RESET
POR
signal. The VBO circuitry rejects very short negative brown-out pulses to prevent spurious
RESET events. VBO operation is displayed in
Figure 4
on page 34. The signals in this fig-
ure are not drawn to scale and are for displaying purposes only.
