722 / 1348 page ![]() Chapter 19 S12X Debug (S12XDBGV2) Module MC9S12XDP512 Data Sheet, Rev. 2.21 724 Freescale Semiconductor information (R/W, S/D etc.). The numerical suffix indicates which tracing step. The information format for loop1 mode is the same as that of normal mode. Whilst tracing from XGATE or CPU only, in normal or loop1 modes each array line contains data from entries made at 2 separate times, thus in this case the DBGCNT[0] is incremented after each separate entry. In all other modes, DBGCNT[0] remains cleared while the other DBGCNT bits are incremented on each trace buffer entry. XGATE and S12X_CPU COFs occur independently of each other and the profile of COFs for the 2 sources is totally different. When both sources are being traced in Normal or Loop1 mode, for each single entry from one source, there may be many entries from the other source and vice versa, depending on user code. COF events could occur far from each other in the time domain, on consecutive cycles or simultaneously. If a COF occurs in one source only in a particular cycle, then the trace buffer bytes that are mapped to the other source are redundant. Info byte bit CDV/XDV indicates that no useful information is stored in these bytes. This is the typical case. Only in the rare event that both XGATE and S12X_CPU COF cycles coincide is a valid trace buffer entry for both made, corresponding to the first line for mode "Both Normal/Loop1" in Table 19-39. Single byte data accesses in detail mode are always stored to the low byte of the trace buffer (CDATAL or XDATAL) and the high byte is cleared. When tracing word accesses, the byte at the lower address is always stored to trace buffer byte3 and the byte at the higher address is stored to byte2 Table 19-39.
