應(yīng)用軟件根據(jù)BYPASS信號(hào)的值來(lái)決定是否使用PLL。如果使用PLL，那么它總是輸出一個(gè)200MHz的時(shí)鐘信號(hào)，并且聯(lián)合系統(tǒng)分頻器（SYSDIV）共同產(chǎn)生系統(tǒng)時(shí)鐘。饋送到PWM模塊的時(shí)鐘由系統(tǒng)時(shí)鐘提供。如果應(yīng)用中需要較低的PWM時(shí)鐘，那么在時(shí)鐘信號(hào)到達(dá)PWM模塊前可以使用PWM分頻器（PWMDIV）先分頻。ADC時(shí)鐘使用一個(gè)時(shí)鐘源（source）為200MHz的常量分頻器，這就意味著如果要使ADC時(shí)鐘的工作頻率保持在14-18MHz范圍內(nèi)，必須使能并使用PLL。
