nPORRST 46 Input Pull Down 100uA Power-on reset, cold reset
External power supply
monitor circuitry must
drive nPORRST low when
any of the supplies to the
microcontroller fall out of
thespecified range. This
terminal has a glitch filter.
See Section 4.8.
nRST 116 I/O Pull Up 100uA System reset, warm reset,
bidirectional.
The internal circuitry
indicates any reset
condition by driving nRST
low.
The external circuitry can
assert a system reset by
driving nRST low. To
ensure that an external
reset is not arbitrarily
generated, TI
recommends that an
external pull-up resistor is
connected to this terminal.
This terminal has a glitch
filter. See Section 4.8.
