USART
Single USART
2512K–AVR–01/10
The Universal Synchronous and Asynchronous serial Receiver and Transmitter
(USART) is a highly flexible serial communication device. The main features are:
•
•
•
•
•
•
•
•
•
•
•
•
The ATmega8515 has one USART. The functionality for the USART is described below.
Note that in AT90S4414/8515 compatibility mode, the double buffering of the USART
Receive Register is disabled. For details, see “AVR USART vs. AVR UART – Compati-
bility” on page 137.
A simplified block diagram of the USART Transmitter is shown in Figure 64. CPU acces-
sible I/O Registers and I/O pins are shown in bold.
