OFF,
OFF
OFF,
OFF,
USART3 is connected to ARDUINO
ON, ON
ON SDMMC data (D0/D1) signals are connected to the ST morpho connector (CN12).
SDMMC data signals (D0/D1) are not connected to the ST morpho connector (CN12) to
OFF
avoid stubs on SDMMC data signals.
These pins can be used as GPIOs on the ST morpho connector (CN12). (SB27 and SB28
ON, ON
must be OFF).
OFF, These pins are used as D- and D+ on the USB connector (CN13). (SB27 and SB28 must
OFF be ON). (Default).
ON VDD33_USB_2 pin of STM32H5 is connected to 3V3.
OFF VDD33_USB_2 pin of STM32H5 is not connected.
PB13 and PB14 are used as the UCPD_CC1 and UCPD_CC2 signals.
ON, ON
(SB12 must be OFF)
PB13 and PB14 can be used as GPIOs on the ST morpho connector (CN12). (SB12 must
be OFF).
OFF,
OFF
PB13 can be used as the I2S_2_CK signal on the ST Zio connector (CN7) (SB12 must be
ON).
ON PA9 is connected and used as the UCPD_DBn signal (dead battery detection).
OFF PA9 can be used as GPIO on the ST morpho connector (CN12).
ON VDD_MMC_1 pin of STM32H5 is connected to VDD_MCU.

PB3 is connected on ST Zio connector (CN7) and can be used as I2S_3_CK/ SPI1_SCK
ON, OFF
signals.
OFF,
PB3 can be used as GPIOs on the ST morpho connector (CN12).
OFF
These pins are used as RMII signals and connected to Ethernet PHY. SB10 must be OFF.
ON
PB15 can be used as I2S_2_SD on ST Zio (pin 3 of CN7) if not used on the ST morpho.
These pins can be used as GPIOs on the ST morpho connectors. PB15 can be used as
