4.17
The MCF5445x includes three UART modules. The M54455EVB provides two standard RS232 line
drivers on UART0 and UART1, connected to a dual, stacked DB9 serial port connector (male). The RS232
null-modem cable provided in the kit can connect the serial ports to a host PC.
The EVB also supplies an optional USB-to-UART bridge (Silicon Labs CP2102) to interface with
MCF5445x's UART0. If using this option, a USB type B connector can interface with a host PC instead of
the standard RS232 connector. A custom virtual COMM port driver may be required on the host PC and
