1.3.5
The MCF5407 contains two UARTs, which function independently. One UART has been enhanced to
provide synchronous operation and a CODEC interface for soft modem support. Each UART can be clocked
by the system bus clock, eliminating the need for an external crystal. Each UART module interfaces directly
to the CPU, as shown in Figure 2.
Each UART module consists of the following major functional areas:
In addition, UART1 is enhanced to provide a CODEC interface for soft modem support. UART1 can be
programmed to function like UART0 or in one of three following modem modes:
Each UART contains an on-chip baud-rate generator, which provides both standard and nonstandard baud
rates. Data formats can be 5, 6, 7, or 8 bits with even, odd, or no parity, and up to 2 stop bits in 1/16
increments. The UARTs include the following transmit and receive FIFO buffers:
The UART modules also provide several error-detection and maskable-interrupt capabilities. Modem
support includes request-to-send (RTS) and clear-to-send (CTS) lines.

In UART1, the Tx and Rx FIFOs can hold the following:
— 32 1-byte samples when programmed as a UART or as an 8-bit CODEC interface
— 16 2-byte samples when programmed as a 16-bit CODEC interface
— 16 20-bit samples when programmed as a Digital AC ’97 Controller
