Dear Sir,
At section 9.4.1.1 on page 59 of d/s, it has the following description:
"a brown-out event occurs, when the supplies have dipped below the minimum operating voltages."
Does it mean that three AVDD(to AVSS), DVDD(to DGND) or IOVDD(to DGND) voltages are monitored and if even only one of them is detected below MIN voltage, it goes into POR?
And above DVDD in IOVDD to GND means IOVDD < DVDD? It is NOT 2.7V but 3.3V when DVDD=3.3V?
Operation condition is specifically
AVDD=5V
DVDD=IOVDD=3.3V
AVSS=DGND=0V
Best regards,
Masa
