Mask ROM and EVA device:

CMOS Hysteresis input pin

Flash device:

CMOS input pin

12 V withstand (for MD [2:0])

CMOS Hysteresis input pin

Pull-up resistor value: 50 k

 approx.

High-speed oscillation circuit:

■ Programmable between oscillation mode (external crystal

or resonator connected to X0/X1 pins) and Fast external

Clock Input (FCI) mode (external clock connected to X0

pin)

■ Feedback resistor = approx. 2 * 0.5 M.

Feedback resistor is grounded in the center when the

oscillator is disabled or in FCI mode.

Low-speed oscillation circuit:

■ Feedback resistor = approx. 2 * 5 M.

Feedback resistor is grounded in the center when the

oscillator is disabled.
