    Table 3.1 Summarize of control word (D0 - D4) and mode state (Mode 0 - Mode 15) Register Structure The PET-48DIO needs two bytes of I / O address to operate, the first byte is ports' index select and the second byte is ports' data read/write.
  • Page 28 For example, If you defined the PET-48DIO's I/O port address as 300H, then the index select register is 300H, and Data Read/Write register is 301H. The relationship of ports' index select and ports' data read / write shows a s figure.
