Crystal connection pin for the subsystem clock os-
cillator. When the external clock is used, input the
external clock to pin XT1. In this case, pin XT2 must
be left unconnected. Pin XT1 can be used as a 1-
bit input (test) pin.
System reset input (low level active)
Internally connected. Connect directly to V
