READI Module
24.12 Watchpoint Support
This section details the watchpoint support features of the READI module.
The READI module provides watchpoint messaging via the auxiliary port, as defined by the IEEE-ISTO
5001-1999.
READI is not compliant with all the breakpoint/watchpoint requirements defined in the IEEE-ISTO 5001
standard. Watchpoint trigger and breakpoint/watchpoint control registers are not implemented.
Watchpoint setting via READI can only be done using the BDM protocol.
24.12.1 Watchpoint Messaging
The READI module provides watchpoint messaging using IEEE-ISTO 5001-1999 defined public
messages. The watchpoint status signals from the RCPU are snooped, and when watchpoints occur, a
message is sent to the signal output formatter to be messaged out (the general message queue is bypassed
to prevent watchpoint messages from being cancelled in the event of a queue overflow). The watchpoint
