• Manufacturer Part Number: MC68HC711PH8
• Description: High-density Complementary Metal Oxide Semiconductor (HCMOS) Microcomputer Unit
• Manufacturer: Motorola

The MC68HC11PH8 has up to 54 input/output lines and 8 input-only lines, depending on the
operating mode. To enhance the I/O functions, the data bus of this microcontroller is
non-multiplexed. The following table is a summary of the configuration and features of each port.

Do not confuse pin function with the electrical state of that pin at reset. All
general-purpose I/O pins that are configured as inputs at reset are in a high-impedance
state and the contents of the port data registers are undefined; in port descriptions, a
‘u’ indicates this condition. The pin function is mode dependent.
