23.1.1.3
There is one special case when although queue flush information is expected on the VF pins, (according
to the last value on the VF pins), regular instruction type information is reported. The only instruction type
information that can appear in this case is VF = 111, branch (direct or indirect) NOT taken. Since the
maximum queue flushes possible is five, it is easy to identify this special case.
23.1.2
When entering debug mode an interrupt/exception taken is reported on the VF pins, (VF = 100) and a cycle
marked with the program trace cycle is made visible externally.
When the CPU is in debug mode, the VF pins equal ‘000’ and the VFLS pins equal ‘11’. For more
information on debug mode refer to
If VSYNC is asserted/negated while the CPU is in debug mode, this information is reported as the first VF
pins report when the CPU returns to regular mode. If VSYNC was not changed while in debug mode. the
first VF pins report will be of an indirect branch taken (VF = 101), suitable for the rfi instruction that is
being issued. In both cases the first instruction fetch after debug mode is marked with the program trace
cycle attribute and therefore is visible externally.
23.1.3
There are cases when non-branch (sequential) instructions may effect the machine in a manner similar to
indirect branch instructions. These instructions include rfi, mtmsr, isync and mtspr to CMPA-F, ICTRL,
ECR and DER.
These instructions are marked by the CPU as indirect branch instructions (VF = 101) and the following
instruction address is marked with the same program trace cycle attribute as if it were an indirect branch
target. Therefore, when one of these special instructions is detected in the CPU, the address of the
following instruction is visible externally. In this way the reconstructing software is able to evaluate
correctly the effect of these instructions.
23.1.4
When program trace is needed, the external hardware needs to sample the status pins (VF and VFLS) each
clock cycle and the address of all cycles marked with the program trace cycle attribute.
