Whether is the GPIO table missing default value?

Hi,

When I read GPIO pin and alternate function table, it is not seen the default power-on values. Here is the picture:

Is there something different from table content?

Hello Robert,

At Power On all GPIO are configured in Input mode except for the Pins that shall be JTAG or Boot Loader Interface

Hi Amit,

Sorry for the "nitpick" but do not those pins w/"special" default status: (i.e. UART, I2C, SPI) - usually residing w/in Port A - deserve mention?

Hello cb1,

They are distributed amongst Port A, Port B and based on USB and pin package on another port.

Hi Amit,

Yes - your knowledge of the (many) different MCU versions is unmatched. Yet - do not those "special-pin defaults" (I2C, SPI, UART etc.) violate the, "all GPIO as inputs" (earlier) writing?

Hello cb1,

That is given in the GPIO Section of the Data Sheet on Special pins.
