P2_Sync_Data_IO_Activation If flag is set, the logic value at the parame-
ter pin P2 determines whether the Syn-

tive.
If flag is not set, the Synchonous Data IO
Mode is always active if it was enabled by
the Synchronous_Data_IO flag.

ID_Code1_Protect
If flag is set, ID_Code_Extension_1 is write
protected for user access.
In Extended Address Mode, only Bits 2…0
are blocked. Bit 3 is used for A/B slave
selection and must remain user accessi-
ble.
