READI Module
24.7.7
The READI signals support 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.

Steps to Enter READI (Nexus) mode:
To exit READI mode:
24.7.7.1
To enable RCPU development access via the READI signals, the reset sequence outlined below should be
used:
Refer to
24-36
1. Negate PORESET while holding JCOMP/RSTI low.
2. Configure TMS/EVTI and TDI/DSDI/MDI[0] while JCOMP/RSTI is low. (EVTI = low to enable
3. Negate JCOMP/RSTI.
4. If MDI[0] is high at JCOMP/RSTI negation, then full port mode is enabled otherwise Reduced
1. Reassert JCOMP/RSTI to disable READI.

mode is selected.
Assert READI reset (RSTI), event-in (EVTI) and system reset (HRESET)
Negate RSTI
Upon negation of RSTI, tool should configure the DOR, DME, and DPA fields in the DC register
to desired setting.
Tool negates HRESET at least 16 system clocks after receiving the device ready message
