capacitance table.
7.3.3
IO Status During PORRST
IO buffer condition during power-on-reset (nPORRST is low): All I/O pins, except nRST, are configured as
High-impedance while nPORRST is low and immediately after nPORRST goes high. The FlexRay
FRAYTX1 and FRAYTX2 pins are high impedance (high-Z) while nPORRST is low, and are output high at
latest 1024 oscillator cycles after nPORRST goes high; the FlexRay FRAYTXEN1 and FRAYTXEN2 pins
are high impedance (high-Z) while nPORRST is low, and output high immediately after nPORRST goes
high.
IO pullup/pulldown condition during power-on-reset: all internal pullups and pulldowns on input pins are
disabled when nPORRST is low, and become active immediately after nPORRST goes high. Pins that are
listed with "programmable" have programmable pullups or pulldowns. The default value after reset is listed
underneath "programmable" in the following table. The exceptions are nPORRST, nRST, nTRST and
TEST pins. The pulls on these pins will be active during power-on-reset.
