In MODE 1, each group may be programmed to have 8 lines of input or output. MODE 2 is a strobed bi-directional bus configuration. The is a 40 pin integrated circuit IC , designed to perform a variety of interface functions in a computer environment. All information read from and written to the occurs via these 8 data lines. All peripheral ports are set to the input mode. They can be connected to peripheral devices. There are several different operating modes for the and these modes must be defined by the CPU writing programming or control words to the device The line group of port C consists of two 4 bit ports.
One of the 4 bit group is associated with group A control and the other 4 bit group with group B control device signals. The upper 4 bits of port C are associated with group A control while the lower 4 bits are associated with group B control. These blocks provide the electrical interface between the Z80 and the The internal path being enabled depends on the type of operation performed by the Z If bit 7 of the control word is a logical 1 then the will be configured.
