FUNCTIONAL DESCRIPTION

Pin Functional Description

• OS1 (Pin 39), OS2 (Pin 40), f (Pin 41)

These are pins for the RC oscillation circuit. Connect external resistors and a capacitor as shown

below. When inputting the external clock pulse, input it to OS1 pin. OS2 and f pins should

be left open.

The relationship between the frame frequency fFR and internal clock frequency ff is expressed

by the following equation:

(RC oscillation frequency = internal clock frequency)

ff = 4 x 16 x fFR

In addition, the relationship between the frame frequence fFR and frame synchronizing signal

frequency fFRAM is expressed by the following equation.

fFRAM = fFR/2

• CS0 (Pin 30), CS1 (Pin 31)

Chip select input pins. Master or slave mode is selected by CS0 and CS1 as shown in the table

below. A maximum of 4 chips can be connected in this manner. Use the master mode when

using a single device.
