UART
Overview
Architecture
PS017609-0803
The Universal Asynchronous Receiver/Transmitter (UART) is a full-duplex communica-
tion channel capable of handling asynchronous data transfers. The Z8F640x family device
contains two fully independent UARTs. The UART uses a single 8-bit data mode with
selectable parity. Features of the UART include:
•
•
•
•
•
•
•
•
The UART consists of three primary functional blocks: transmitter, receiver, and baud rate
generator. The UART’s transmitter and receiver function independently, but employ the
same baud rate and data format. Figure 67 illustrates the UART architecture.
