Notes:
• The single chip mode is all available as the port.
• The upper addresses, (WRL), (WRH), (HAK), HRQ, RDY, and CLK are used as a port according to the function selection.
• While using the multiplex, you can use the upper addresses A23 to A20 as a port or PPG3 to PPG0.
• While using the non-multiplex, you may not use the reload time ch0/ch1/ch2, UART ch0/ch1. It works as an address.
