Clock Generation Circuit
−
Low-speed clock
Internal low-speed RC oscillation: Approx.32.768 kHz
External low-speed crystal oscillation: 32.768 kHz crystal resonator is connectable (ML62Q1500 and
ML62Q1700 group)
3 modes are available for the crystal oscillatiion
× Tough mode: Largest oscillation allowance to make highest resistance against leakage between the pins
× Standard mode: Standard oscillation allowance and current consumption
× Low power current mode: Smaller oscillation allowance than standard mode to make lower current
consumption
−
High-speed clock
PLL oscillation: 24MHz/16MHz is selectable by code option
−
WDT(Watch Dog Timer) clock
Internal low-speed RC oscillation: Aprox. 1kHz
The WDT independent clock or the divided clock of internal low-speed 32.768kHz RC oscillation clock is
selectable by the code option.
