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).
