Serial Input/Output

The unit has two serial ports compatible with RS232 serial standards at data rates
up to 921 Kbps. The serial I/O signals are 3.3V CMOS logic level and pins are 5V
tolerant. Serial signals connect to the OEM CPU/UART. For evaluation and prototype
work, it is convenient to have an external RS-232 interface that can connect to the
serial port on a PC. The MatchPort Demo Board has RS-232/422/485 transceivers to
implement this external interface.
If desired, use the CPs to create a DTE or DCE-style interface using any three
available CPs. To create these interfaces, connect the signals according to Table 2-2
and Table 2-4.
Note: CPx, and CPy are any of the available CPs.
