Function
In the
PD78C11A(A) and 78C12A(A), the MODE0 pin is set to “0” (low) and the MODE1
pin is set to “1” (high)(Note).
In the
PD78C10A(A), the MODE0 and MODE1 pins are used to select one of three external
memory sizes: 4 Kbytes, 16 Kbytes, or 64 Kbytes.
If MODE0 and MODE1 are both set to “1”(Note), a control signal is output synchronously
with ALE.
This is a falling edge-triggered nonmaskable interrupt input pin.
INT1 is a rising edge-triggered maskable interrupt input pin. It is also an AC-input, zero-
cross detection pin.
These are eight analog inputs to the A/D converter. AN4 to AN7 can also be used as inputs
for falling edge detection.
This pin can be used as a reference voltage input for the A/D converter or as a control
pin for A/D converter operation.
This is the power supply pin for the A/D converter.
This is the ground pin for the A/D converter.
These are the crystal pins for the system clock oscillator. X1 inputs an external clock.
X2 inputs the inverted clock from X1.
This is the system reset input pin (active low).
This is the control signal input pin during hardware STOP mode. Low-level input stops
the system clock oscillator.

Note
These must be pulled up using a pull-up resistance value (R) of 4 (k
) ≤ R ≤ 0.4 tCYC (k). (tCYC is in
ns units.)
Remark
On-chip pull-up resistors for Ports A, B, and C are available as mask options on the
PD78C11A(A)
or 78C12A(A).
