PC31UD69V630TF Datasheet
Reading from the device is accomplished by taking Chip Enable (CE) and Output Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory location specified by the address pins will appear on l/00 to l/07. If Byte High Enable (BHE) is LOW, then data from memory will appear on l/08 to l/Ois. See the truth table at the back of this data sheet for a complete description of read and write modes.

The quad-monitor is also capable of sensing AC ripple or oscillation. This feature is gained by connecting a capacitor across the potentiometer as shown in Figure 13. While the DC voltage is divided by the potentiometer the AC is conducted directly to the input by the capa- citor. The calibration monitor will respond to a peak AC voltage of 120 mV with the 5% setting, 230 mV with the 10% setting, and 420 mV with the 20% setting. The value of the capacitor is solely determined by the lowest desired frequency and the value of the external potentiometer. SETTING UP IN BAND VOLTAGES
