Serial Module Overview
14.2 Serial Module Overview
The MCF5307 contains two independent UART modules, whose features are as follows:
14.3 Register Descriptions
This section contains a detailed description of each register and its specific function.
Flowcharts in Section 14.5.6, “Programming,” describe basic UART module programming.
The operation of the UART module is controlled by writing control bytes into the
appropriate registers. Table 14-1 is a memory map for UART module registers.
14-2
• Each can be clocked by BCLKO, eliminating a need for an external crystal
• Full-duplex asynchronous/synchronous receiver/transmitter channel
• Quadruple-buffered receiver
• Double-buffered 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
• Four maskable interrupt conditions
• UART0 and UART1 have interrupt capability to DMA channels 2 and 3,
• 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
— 5–8 data bits plus parity
— Odd, even, no parity, or force parity
— One, one-and-a-half, or two stop bits
loop-back, or remote loop-back mode
respectively, when either the RxRDY or FFULL bit is set in the USR.
