Notes: 1. The external bus trace interface connector installed on the user system must be as close
to the MCU as possible.
2. Wiring pattern of clock lines (CKO)
The followings are notes on wiring of clock lines for the E200F trace interface signals.
Take them into consideration when designing the user system to embed suitable clock
lines.
(a) Clock lines must be as short as possible.
(b) Clock lines must be surrounded by the GND pattern for protection so that the
signals will be of low-impedance.
(c) Other layers next to the layer with clock line wiring should have solid patterns
of GND/VCC so that the signals will be of low-impedance.
(d) To prevent affect by the crosstalk noise, other signal patterns must not be
embedded along with the clock lines.
