troller selects PDB as destination for serial data.
After 24 bits have been received, the PDB register drives the PDB. The OnCE con-
troller releases the chip from the debug mode, the chip executes the MOVE
instruction, and the contents of the register specified in the instruction are loaded in
the GDB REGISTER. The signal that marks the end of the instruction returns the
chip to the debug mode.
