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
