Chapter 37. System Development and Debugging
37-31
Part VI. Debug and Test
Table 37-10 shows the encoding of trap data shifted into the (through DSDI).
Table 37-11 shows the encoding of debug port command data shifted into the development
port shift register.
The watchpoint trap enables and VSYNC functions are described in Section 37.2,
ÒWatchpoints and Breakpoints Support,Ó and Section 37.1, ÒTracking Program Flow.Ó The
debug port command function allows the development tool to either assert or negate
breakpoint requests, reset the processor, activate or deactivate the fast download procedure.
37.3.2.4.2 Serial Data Out of Development Port
In trap enable mode there is no data from the core out of the development port. Data out of
the development port in the trap enable mode is shown in Table 37-12.
