• Port3 (P30-P36) can be selected for input or output by each 1 bit. Set for input when reset. And it can be set C-MOS or Nch-OD by each 1 bit
in option.
• Port7 (P70-P73) can be selected for input or output by each 1 bit. Set for input when reset.
• Port8 (P80-P87) can be selected for input or output by each 1 bit. Set for input when reset.
• PortA (PA0-PA5) can be selected for input or output by each 1 bit. Set for input when reset. And it can be set C-MOS or Nch-OD by each 1
bit in option.
• PortB (PB0-PB7) can be selected for input or output by each 1 bit. Set for input when reset. And it can be set C-MOS or Nch-OD by each 1
bit in option.
• PortC (PC0-PC7) can be selected for input or output by each 1 bit. Set for input when reset. And it can be set C-MOS or Nch-OD by each 1
bit in option.
• PortE and PortF can be selected for input or output by each 2 bits.
• In case of without RDS, it is best that RDSDATA and RDSCLK are assigned as I/O port which can be set output and output low level.
