Caution When X2 and XT1 are wired in parallel, the crosstalk noise of X2 may increase with XT1, resulting in
malfunctioning.
Remark When using the subsystem clock, replace X1 and X2 with XT1 and XT2, respectively. Also, insert resistors in series on
the XT2 side.
(e) Wiring near high alternating current
(f) Current flowing through ground line of oscillator
(potential at points A, B, and C fluctuates)
