sampling the value of the status pins (VF and VFLS), and the address of the cycles marked as program
trace cycle immediately after the VSYNC report on the VF pins.
The last two instructions reported on the VF pins are not always valid. Therefore at the last stage of the
reconstruction software, the last two instructions should be ignored.
23.1.4.5
In order to store all the information generated on the pins during program trace (five bits per clock + 30
bits per show cycle) a large memory buffer may be needed. However, since this information includes
events that were canceled, compression can be very effective. External hardware can be added to eliminate
all canceled instructions and report only on branches (taken and not taken), indirect flow change, and the
number of sequential instructions after the last flow change.
23.1.5
Instruction fetch show cycles are controlled by the bits in the ICTRL and the state of VSYNC. The
following table defines the level of fetch show cycles generated by the CPU. For information on the fetch
show cycles control bits refer to
23.2
Watchpoints, when detected, are reported to the external world on dedicated pins but do not change the
timing and the flow of the machine. Breakpoints, when detected, force the machine to branch to the
appropriate exception handler. The RCPU supports internal watchpoints, internal breakpoints, and
external breakpoints.
Internal watchpoints are generated when a user programmable set of conditions are met. Internal
breakpoints can be programmed to be generated either as an immediate result of the assertion of one of the
internal watchpoints, or after an internal watchpoint is asserted for a user programmable times.
Programming a certain internal watchpoint to generate an internal breakpoint can be done either in
