The state of port G pin 7 (PG7) at reset is mode dependent. In
single-chip or bootstrap modes, it is a high-impedance input; its data
direction can be changed through DDRG. In expanded and special test
modes, PG7 functions as the R/W line to control the direction of data flow
between the MCU and external memory devices.
Port G pins (PG[6:0]) reset to high-impedance inputs in any mode. Data
direction can be changed through DDRG. Port G bits [5:0] can serve as
memory expansion address lines (see
expanded and special test modes. M68HC11KS devices do not contain
these pins.
All eight port G pins have selectable internal pullup resistors (see
