4.6.2 DDRD — Data direction register for port D
4.7 Port E
MC68HC11P2 — Rev 1.0
Data direction D (DDRD)
Bits [7:6] — Reserved; always read zero
DDD[5:0] — Data direction for port D
Port E is an 8-bit input-only port. In addition to their input capability, port
E pins are shared with A/D functions, as shown in the following table.
On reset the pins are configured as general purpose high-impedance
inputs.
