Signal Descriptions
2.5.2
The MPC561/MPC563 has a 10 pin BDM port. See
The BDM mode is entered by the following sequence of events:
BDM mode is exited by:
2.5.3
The READI module signals support the Nexus (IEEE-ISTO 5001-1999) auxiliary port interface for debug.
There are two modes available: full port mode and reduced port mode. Reduced port mode allows for a 1
bit input stream and a 2 bit output stream. Full port mode allows for a 2-bit input stream and an 8-bit output
stream. If MDI0 is held high when Nexus mode is enabled, full port mode will be used during Nexus
debug. If MDI0 is held low when Nexus mode is enabled, reduced port mode will be used. See
for Nexus mode selection.
The Nexus interface is entered by the following sequence of events:

JCOMP/RSTI
JCOMP/RSTI
Hold DSCK high at reset negation (SRESET)
Configure DSDI to select BDM clock mode, within 8 clocks of reset negation
Reset the device by asserting PORESET/TRST or HRESET
Hold JCOMP/RSTI low while negating PORESET/TRST
Hold TMS/EVTI low to enable Nexus mode and configure TDI/DSDI/MDI0 for full or reduced
port mode. Both of these should be done at least 4 clocks before driving JCOMP/RSTI high
