    Port 0 :

    PC0 = 0xffff

    PC1 = 0xffff

    PC2 = 0x0

    PD = 0xe0ff

    Port 1 :

    PC0 = 0xffff

    PC1 = 0xffff

    PC2 = 0x0

    PD = 0xfcff

    Port 2 :

    PC0 = 0xffff

    PC1 = 0xffff

    PC2 = 0x1

    PD = 0xff0f

    These are the values that can be derived from the Reference Manual, if I'm understanding it correctly.

    (On my STR711, however, it seems that P0.15 is configured for TTL input at reset. This is not mentionned in the docs.)

    Can anybody at ST confirm the values ?

    Thank you,

    where did you find the reset value in the reference manual ?

    (I didn't find it, there's just an asterisk)

    The values are not explicitely written in the Reference Manual, but you can calculate them using the information in the Device Pin Description table (see page 22).
