*
Vpp
is
pin 7 on the MC68705R3 and MC68705R5 and is connected
to
VCC
in the normal operating mode.
In
the MC6805R2, pin 7
is
connected
to
VSS in the normal operating mode. The user must allow for this difference when emulating the MC6805R2 ROM-based
MCU.
*
*Due
to internal biasing. this input (when not used) floats
to
approximately 2.0
V.
NOTE: Port D analog inputs. when selected.
