When switching on a new, unprogrammed STM32L431, PA6 turns hard to output high.
This is SPI1 MOSI.
AN2606 should say this out aloud.
I know the 'G0 have this too, and AN2606 says this for them, although quite quietly and confusingly in a footnote.

Hi @waclawek.jan,
I would inform you that this issue is fixed in the new release of AN2606 (Rev 63).
Thank you for your important contribution.

Hi @waclawek.jan,
"SPI Tx (MISO) is handled by DMA. On the bootloader start-up after SPI initialization as soon as the bit DMATx enable on SPI CR2 register is set to 0x1, the MISO line is set to 3.3 V." => This note is available in the AN2606 for STM32G0, STM32G4 and STM32L412xx/422xx, but not for STM32L43.
I escalated this feedback to add this note for STM32L43x (via Internal ticket number: 173607)
Thank you again for the continued feedback; it is much appreciated! 🙂
