Depending on the delay of the next applied reset,
the MCU can enter a synchronous reset or an
asynchronous reset. If RPD pin is below 2.5V an
asynchronous reset starts, if RPD pin is above
2.5V a synchronous reset starts. (See Section
18.1 - and Section 18.2 -).
Note that an internal pull-down is connected to
RPD pin and can drive a 100 A to 200 A current.
This Pull-down is turned on when RSTIN pin is
low.
To properly use the bidirectional reset features,
the schematic (or equivalent) of Figure 60 must be
implemented. R1-C1 only work for power-on or
manual reset in the same way as explained
previously. D1 diode brings a faster discharge of

C1 capacitor at power-off during repetitive
switch-on / switch-off sequences. D2 diode
performs an OR-wired connection, it can be
replaced with an open drain buffer. R2 resistor
may be added to increase the pull-up current to
the open drain in order to get a faster rise time on
RSTIN pin when bidirectional function is activated.
The start-up configurations and some system
features are selected on reset sequences as
described in Table 38 and Table 39.

different reset ways. Table 39 summarizes the
