ColdFire Module Description
1.3.4
The MCF5307 contains two UARTs, which function independently. 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 2.
Each UART module consists of the following major functional areas:
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 4-byte and 2-byte 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.
BCLKO 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, and remote loopback modes
allow testing of UART connections. The programmable UARTs can interrupt the CPU on various normal or
error-condition events.
1.3.5
The timer module includes two general-purpose timers, each of which contains a free-running 16-bit timer
for use in any of three modes. One mode captures the timer value with an external event. Another mode
triggers an external signal or interrupts the CPU when the timer reaches a set value, while a third mode
counts external events.
The timer unit has an 8-bit prescaler that allows programming of the clock input frequency, which is derived
from the system bus cycle or an external clock input pin (TIN). The programmable timer-output pin
generates either an active-low pulse or toggles the output.
