Pin states in external bus mode
The external bus interface pins become outputs while the device is in the settings initialization (INIT) state.
The pins go to the Hi-Z state while the INITX pin is at the “L” level. The value listed in the table is output when
the INITX pin goes to the “H” level.
The external bus interface output functions for ports 2, 3, 9, E, and F can be disabled by setting EPFR. The
meanings of the following symbols used in the table are:
B : External bus interface function mode (EPFR
= 0)
P : General-purpose port or peripheral function mode (EPFR
= 1)
