Preliminary Data Sheet
18. DebugSIU (DEBUG SERIAL INTERFACE UNIT)
18.1 General
The DebugSIU is a dedicated serial interface unit that is used during debugging. It supports a data transfer rate of up
to 115 kbps. In addition to the DDIN and DDOUT I/O pins, it supports the DCTS# and DRTS# pins that are used for
hardware flow control. These pins can be used as a general-purpose output port when DSIU is not used.
