ColdFire Module Description
1.3.5 UART Modules
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. Either 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 1-2.
Each UART module consists of the following major functional areas:
UART1 is enhanced to provide a CODEC interface for soft modem support. UART1 can be
programmed to function like UART0 or in one of following modem modes:
Each UART contains an programmable clock-rate generator. 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.
CLKIN provides the time base through a programmable prescaler. The UART time scale
can also be sourced from a timer input. Full-duplex, auto-echo loopback, local loopback,
