PLL PROGRAM SUMMARY

MCU ( MICOM ) SERIAL INTERFACE ( MSB : 1ST INPUT )

Use CLK (Pin 7 ), DATA (Pin 8 ) , EN (Pin 9 ) terminals for program. DATA and CLK terminals are used for loading

data to internal Shift - Register. When EN terminal is ‘Low’ It is possible to program TX-Channel Counter, RX -

Channel Counter and various control functions of PLL. When EN terminal is ‘High’ Program 1st Local Oscillator

Capacitor Selection in receiver for U.S.A - 25 CH function.

— TX - Register, RX-Register, Control Register

— Reference - Register

— RECEIVER -1st local oscillator internal capacitor selection register & low battery detector voltage register
