NOTE: The device supports continuous operation with V
CC
= V
SS
while V
IO
is fully within its specification. During this time, the
general-purpose I/Os that reside on the V
IO
supply domain are configured as inputs and pulled down to V
SS
through
their internal pulldown resistors. RST/NMI is high impedance. BSLEN is configured as an input and is pulled down to
V
SS
through its internal pulldown resistor. When V
CC
reaches above the BOR threshold, the general-purpose I/Os
become high-impedance inputs (no pullup or pulldown enabled), RST/NMI becomes an input pulled up to V
IO
through
its internal pullup resistor, and BSLEN remains pulled down to V
SS
through its internal pulldown resistor.
