Figure 109. Transmit and Receive Data Path
The functional capabilities of the Z80 SIO are described in two ways: as a
data communications device, and as a Z80 family peripheral.
As a data communications device, The S80 SIO transmits and receives
serial data, and meets the requirements of various data communications
protocols. As a Z80 family peripheral, it interacts with the Z80 CPU and
other Z80 peripheral, circuits, and shares their data, address and control
