with each port pin, see the
alternate functions, it is recommended to use word data mode instructions to perform
simultaneous Writes to the port alternate function high and low registers.
Table 19. Alternate Function Enabling
Setting the bits in the Port A–H output control registers (see Table 20) to 1 configures the
specified port pins for open-drain operation. These registers affect the pins directly and as
a result, alternate functions are also affected. Enabling the I
configures the SCL and SDA pins as open-drain; independent of the setting in the output
control registers that have the SCL and SDA alternate functions.

Note: x indicates the register bits from 0 through 7.
AFH[x]
Do not enable alternate functions for GPIO port pins which do not also offer an
associated alternate function. Failure to follow this guideline will result in unde-
fined operation.
