from IDLE mode
-
10 interrupt sources supporting to wake up the
CPU in power-down mode
-
Slow-frequency mode and sub-frequency mode
supporting low-speed MCU operation
-
RTC mode supporting real-time clock (RTC) to
wake up the CPU in power-down mode

Monitor mode supporting BOD1 to wake up the
CPU in power-down mode
Operating frequency range: up to 25 MHz
-
External crystal oscillator mode, 0
–12 MHz at
2.0
–3.6 V and 0–25 MHz at 2.4–3.6 V
-
CPU operating frequency can reach 12 MHz at
1.8-3.6 V and 25 MHz at 2.2-3.6 V
