(17) Port type 12
Port type 12 provides a general purpose I/O port with digitally filtered peripheral input function and
peripheral output function. This type is similar to the port logic type 1S, but all port registers are
write protected against unintended change due to system or software malfunction. Writing to the
port registers of type 12 is only possible immediately after a write access to the PRCMD register.
