LSE (32.768 kHz low-gudun waje crystal), goyan bayan uku iya aiki halaye. Hakanan ana iya saita LSE a yanayin wucewa don agogon waje.
LSI (32 kHz low-gudun ciki RC), kuma ana amfani dashi don fitar da mai sa ido mai zaman kansa. Daidaiton agogon LSI shine ± 5% daidaito. Ana iya raba agogon LSI da 128 don fitar da 250 Hz azaman agogon tushe.
Tushen agogo na gefe: da yawa na gefe suna da nasu agogo mai zaman kansa ko wane agogon tsarin. PLLs guda uku, kowannensu yana da fitowar masu zaman kansu guda uku suna ba da damar mafi girman sassauci, na iya samar da agogo masu zaman kansu don ADC, USB, SDMMC, RNG, MDF, ADF, FDCAN1, OCTOPIs da SAIs.
Agogon farawa: bayan sake saiti, microcontroller zai sake farawa ta tsohuwa tare da MSI. Za a iya canza rabon prescaler da tushen agogo ta shirin aikace-aikacen da zaran an fara aiwatar da lambar.
CSS (tsarin tsaro na agogo): ana iya kunna wannan fasalin ta hanyar software. Idan gazawar agogon HSE ta faru, babban agogon yana canzawa ta atomatik zuwa HSI16 kuma ana haifar da katsewar software idan an kunna. Hakanan ana iya gano gazawar LSE kuma yana haifar da katsewa.
Iyawar agogo:
MCO (fitilar agogon microcontroller): yana fitar da ɗayan agogon ciki don amfanin waje ta aikace-aikacen.
LSCO (fitilar agogo mai ƙarancin sauri): yana fitar da LSI ko LSE a cikin duk yanayin ƙarancin ƙarfi (sai dai yanayin VBAT).
Yawancin prescalers suna ba da izinin daidaitawar mitoci AHB da APB. Matsakaicin mitar AHB da yankunan agogon APB shine 160 MHz.
