When shorted with VRB, generates approximately

+0.5V .

Clamp Reference Voltage Input.

Digital ground.

When CLE is low, clamp function is activated.

When CLE is high, clamp function is OFF and only

the usual A/D converter function is active.

By connecting CLE pin to DVDD via a several

hundred Ω resistance, the clamp pulse can be

tested.

When OE is low, data is valid.

When OE is high, D0 to D7 pins are high

impedance.
