Reset Sequence
Electrical Characteristics
Parameter
VDDCORE rise rate to ensure power-
on-reset
VDDCORE fall rate to ensure power-
on-reset
Rising threshold voltage: voltage up
to which device is kept under reset by
POR on rising VDDCORE
Falling threshold voltage: voltage
when POR resets device on falling
VDDCORE
On falling VDDCORE, voltage must
go down to this value before supply
can rise again to ensure reset signal
is released at V
Minimum time with VDDCORE <
V
Time for reset signal to be
propagated to system
Time for Cold System Startup: Time
for CPU to fetch its first instruction
(RCosc not calibrated)
Time for Hot System Startup: Time for
CPU to fetch its first instruction
(RCosc calibrated)
