(3) Protection with Vss pattern
there is a Vss pattern at the same position as the oscillator on the reverse side (solder side) of the
board. This Vss pattern must be connected to the microcomputer’s Vss pin in the shortest possible
distance and must be located away from the other Vss patterns.
For double-sided boards in which the oscillator is mounted on one side (mount side), make sure that
Separate the Vss pattern for oscillator from the Vss supply line.
