Reset pins
There are also two different Reset-IO possibilities. The first one is a General Reset RESET_IN# (P127) and the
other one is a RESET_OUT# (P126).
When the RESET_IN# is driven to Low state (with a delay configurable), the power supply from the Power
Management IC, PMIC, is turned off.
The RESET_OUT# pin is an output signal for sending a Reset to external devices (carrier board peripherals).
The next examples show how to implement each reset. The last figure (Figure 10 Reset Out circuit example)
show how to make a reset to an external circuit, in this case a touch controller (page 24 and page 52 of
SMARC Design Guide respectively V_IO=1V8).
