Serial Module Overview
16.2 Serial Module Overview
The MCF5272 contains two independent UART modules, whose features are as follows:
The MCF5272 UART modules are identical to those on other ColdFire devices, such as the
MCF5206e, with the following exceptions:
16-2
• Each clocked by either URT_CLK or CLKIN, eliminating a need for an external
• Full-duplex asynchronous/synchronous receiver/transmitter channel
• 24-byte FIFO receiver
• 24-byte FIFO transmitter
• Independently programmable receiver and transmitter clock sources
• Programmable data format:
• Each channel programmable to normal (full-duplex), automatic echo, local
• Automatic wake-up mode for multidrop applications
• Eight maskable interrupt conditions
• Parity, framing, and overrun error detection
• False-start bit detection
• Line-break detection and generation
• Detection of breaks originating in the middle of a character
• Start/end break interrupt/status
• Autobaud capability
• The MCF5272 receiver and transmitter FIFOs have been expanded to 24 bytes.
• Interrupts can be programmed to occur at various levels of FIFO fullness on both the
• Autobaud capability has been added to automatically calculate the character
• Registers have been added to increase accuracy in clock generation.
