Frequently Asked Questions

Alternate function pin release conditions

Questions:

For AT32F413/AT32F415/AT32F403A/AT32F407, under what conditions can these alternate function pins be

released for TMR?

Answer：

For example:

When the USART1 is being used, if the user wants to use the alternate function TMR1_CH1 on the

USART1_CK (PA8) pin, he needs to check the table below, where the “CK “ of USART is marked “YES”,

meaning that TMR1_CH1 can be used as alternate function while USART1 is in use, on the condition of

CLKEN=0.

Similarly, if the user wants to use the alternate function TMR1_CH2 on the USART1_TX (PA9) pin, he needs

to check the table below, where the “TX” of USART is marked “NO”, meaning that the TMR1_CH2 cannot be

used as alternate function while USART1 is working.
