Compare 1 interrupt flag If channel CC1 is configured as output: The CC1IF flag is set by hardware to inform application that LPTIM_CNT register value matches the compare register’s value. CC1IF flag can be cleared by writing 1 to the CC1CF bit in the LPTIM_ICR register.

0 (B_0x0): No match

1 (B_0x1): The content of the counter LPTIM_CNT register value has matched the LPTIM_CCR1 register’s value

Autoreload match ARRM is set by hardware to inform application that LPTIM_CNT registers value reached the LPTIM_ARR registers value. ARRM flag can be cleared by writing 1 to the ARRMCF bit in the LPTIM_ICR register.

External trigger edge event EXTTRIG is set by hardware to inform application that a valid edge on the selected external trigger input has occurred. If the trigger is ignored because the timer has already started, then this flag is not set. EXTTRIG flag can be cleared by writing 1 to the EXTTRIGCF bit in the LPTIM_ICR register.

Compare register 1 update OK CMP1OK is set by hardware to inform application that the APB bus write operation to the LPTIM_CCR1 register has been successfully completed. CMP1OK flag can be cleared by writing 1 to the CMP1OKCF bit in the LPTIM_ICR register.

Autoreload register update OK ARROK is set by hardware to inform application that the APB bus write operation to the LPTIM_ARR register has been successfully completed. ARROK flag can be cleared by writing 1 to the ARROKCF bit in the LPTIM_ICR register.

Counter direction change down to up In Encoder mode, UP bit is set by hardware to inform application that the counter direction has changed from down to up. UP flag can be cleared by writing 1 to the UPCF bit in the LPTIM_ICR register. Note: If the LPTIM does not support encoder mode feature, this bit is reserved. Refer to Section 26.3.

Counter direction change up to down In Encoder mode, DOWN bit is set by hardware to inform application that the counter direction has changed from up to down. DOWN flag can be cleared by writing 1 to the DOWNCF bit in the LPTIM_ICR register. Note: If the LPTIM does not support encoder mode feature, this bit is reserved. Refer to Section 26.3.

LPTIM update event occurred UE is set by hardware to inform application that an update event was generated. The corresponding interrupt or DMA request is generated if enabled. UE flag can be cleared by writing 1 to the UECF bit in the LPTIM_ICR register. The UE flag is automatically cleared by hardware once the LPTIM_ARR register is written by any bus master like CPU or DMA.

Repetition register update OK REPOK is set by hardware to inform application that the APB bus write operation to the LPTIM_RCR register has been successfully completed. REPOK flag can be cleared by writing 1 to the REPOKCF bit in the LPTIM_ICR register.

Compare 2 interrupt flag If channel CC2 is configured as output: The CC2IF flag is set by hardware to inform application that LPTIM_CNT register value matches the compare register’s value. CC2IF flag can be cleared by writing 1 to the CC2CF bit in the LPTIM_ICR register. Note: If LPTIM does not implement at least 2 channels this bit is reserved. Refer to Section 26.3.

0 (B_0x0): No match

1 (B_0x1): The content of the counter LPTIM_CNT register value has matched the LPTIM_CCR2 register’s value

Compare register 2 update OK CMP2OK is set by hardware to inform application that the APB bus write operation to the LPTIM_CCR2 register has been successfully completed. CMP2OK flag can be cleared by writing 1 to the CMP2OKCF bit in the LPTIM_ICR register. Note: If LPTIM does not implement at least 2 channels this bit is reserved. Refer to Section 26.3.

Interrupt enable register update OK DIEROK is set by hardware to inform application that the APB bus write operation to the LPTIM_DIER register has been successfully completed. DIEROK flag can be cleared by writing 1 to the DIEROKCF bit in the LPTIM_ICR register.
