    1.7.1 Modes of Operation The CP380 uses an 8255 compatible PIO device. The operational modes of the device are described in the following chapters. For further information on the 8255 device con- sult the manufacturer’s data sheet.
  • Page 21 (group A and group B) each containing an 8 bit data port and a 4 bit control/data port are available. The 8 bit ports are used for data input. The CP380-I uses only the PC4 (inter- rupt input for port A) and PC2 (interrupt input for port B) control port lines. All input ports are latched.
