Does STM32F767ZI support Battery charging detection (BCD)?

[ŁJura.1]

Hello team!

I am newbie in STM32 world so probably i am missing something but please clarify this for me. I have found conficting informations:

• Datasheet "DS11532 Rev 7" at p. 47 says "Battery Charging Specification Revision 1.2 support"
• Reference Manual "RM0410 Rev 4", p. 1579 - "supports charging port detection as described in Battery Charging Specification Revision 1.2 on the FS PHY transceiver only."
• the same manual at p. 1638 describes registers related to BCD functionality

however:

• the same manual again says at p. 1581 that this MCU doesn't support BCD at all
• there are no BCD related functions in stm32f7xx_hal_pcd_ex files
• there are no BCD related registers in stm32f767xx.h file

so i am little bit confused about that.

BR.
