This is a low-level active system reset input pin.
NC (Non-connection) pin is not internally connected. Leave this pin open.
Crystal/ceramic resonator connection pins for main system clock oscillation.
For external clock supply, input clock signal to X1 and its inverted signal to X2.
Crystal resonator connection pins for subsystem clock oscillation.
For external clock supply, input the clock signal to XT1 and its inverted signal to XT2.
