.IP "-"
the instruction in MACRO-11 syntax
.IP "-"

.EE
The w11 CPU starts a cache cycle for each read or write, and cancels the
cache request when an ibus access is detected. That's why an 'ib' line
is usually preceded by an 'em' line with the 'cancel' flag, like
.EX
52582 em w 11 00177570 000001 cancel 1000 (1)
52583 ib -- w 11 177570 000001 1 (0) sdreg

.SH EXAMPLES
.IP "\fBtmuconv --t_id --t_em --t_ib tmu_ofile\fR" 4
Produces an output with all instruction decodes and external memory interface
and ibus transactions. The execution of a 'bisb #4,4(r4)' instruction which
accesses the output CSR of a DL11 interface will look like
.EX
429 id 002002 000340 152764 bisb #nnn,nnn(r4) (5)
431 em r 01 00002004 000004 0100 (1)
433 em r 11 00002006 000004 0100 (1)
435 em r 01 00177564 cancel 1100 (1)
436 ib -- rm01 177564 000200 1 (0) to.csr
439 ib -- wm01 177564 000204 1 (0) to.csr
.EE
and shows the canceled em access and the ibus read-modify-write.
.IP "\fBtmuconv --t_id --t_em --t_ib --t_ru tmu_ofile\fR" 4
Like above, in addition, also all register updates are shown. The execution
of a 'cmp (r2),(r4)+' where r2 points to the psw will look like
.EX
934 id 003014 000011 021224 cmp (r2),(r4)+ (9)
936 em r 11 00177776 cancel 1000 (1)
937 ib -- r 11 177776 000011 1 (0) psw
939 ru 0 04 005676 003036 003040 177776 005700 005676*005570 r04
