Note:
(*) All Peripherals in stand-by.
6.4 AC ELECTRICAL CHARACTERISTICS
(T
A
= -40 to +125°C unless otherwise specified)
Notes:
1. Period for which V
DD
has to be connected at 0V to allow internal Reset function at next power-up.
2 An oscillator frequency above 1MHz is recommended for reliable A/D results.
3. Measure performed with OSCin pin soldered on PCB, with an around 2pF equivalent capacitance.
