System reset input
Crystal connect pin for sysem clock oscillation. When an external clock is supplied,
the clock is input to X1 and the inverted clock is input to X2. (X2 can also be left open.)
Positive power supply
GND pin
Not internally connected. Connected to V
In the PD78322, EA pin is normally connected to V
ROM-less mode and accesses the external memory. In the PD78320, this pin should be
fixed to “0” (low level). The EA pin level cannot be changed during operation.
