Function description

to abandon its normal

sequence.

‒

Driven by the master clock, it

has early interrupt warning

function.

‒

It can be configured as a

software or hardware startup

watchdog.

4.11.5.

System tick timer (SysTick)

System tick timer is a standard 24-bit down counter with automatic reloading

function. When the counter is 0, it can generate a masked system interrupt.

4.11.6.

Automatic wake-up timer (WUPT)

WUPT can provide an internal wake-up time reference when MCU enters low

power Active Halt mode. The clock of the time reference is provided by the

internal low-speed RC oscillator clock (LIRC) or the pre-divided HXT crystal

oscillator clock.

BUZZER (Buzzer)

Embedded with a buzzer, when the LS clock works at 128kHz, it can generate a

buzzer signal with frequency of 1kHz, 2kHz or 4kHz.
