/RST
/RST pin is a Schmitt trigger
input pin for hardware device
reset. A “Low” on this pin for
768 clock counter of Internal
RC 22M while the system
I
clock is running will reset the
(ST) _{device. /RST pin has an}
internal pull-up resistor
allowing power-on reset by
simply connecting an external
capacitor to GND.
