Provides
a way to enter Debug mode from an external command
controller (as input) or to acknowledge that the chip has entered

Debug mode (as output). When asserted as an input,
causes
the DSP56300 core to finish the current instruction, save the
instruction pipeline information, enter Debug mode, and wait for
commands from the debug serial input line. When a debug request

pull-up resistor.
DE
is not a standard part of the JTAG Test Access Port (TAP)
Controller. It connects to the OnCE module to initiate Debug mode
directly or to provide a direct external indication that the chip has
entered the Debug mode. All other interface with the OnCE module
must occur through the JTAG port. This input is 5 V tolerant.
