BERR, BKPT, and MODCLK do not have internal pull-ups and must be driven to the desired state during
reset.
Operating mode determines which address and data bus lines are used and which general-purpose I/
O ports are available. The table below summarizes bus and port configuration.
Many pins on the MC68HC16, including data and address bus pins, have multiple functions. Reset val-
ue for these pins depends on operating mode. In expanded mode, the values of DATA[11:0] during re-
set determines the function of these pins. The functions of some pins can be changed subsequently by
writing to the appropriate pin assignment register. Data bus pins have internal pull-ups and must be
pulled low to achieve the desired alternate configuration. The following tables summarize pin configu-
ration options for each operating mode.
