MMDS Commands
A–63MMDS0508 Target Interface
of Term A to H. Without a mask, the ST command uses the unmasked value 0x1F for
the clips.
Each trigger clip line has three options:
H - High
L - Low
X - Don’t Care
The bits of the clips and mask words are:
Bit: Signal:
0 Group A- BRN
1 RED
2 ORG
3 YEL
4 GRN
6 LIR (active low)
;R:Trigger on a read bus cycle only.
;W:Trigger on a write bus cycle only.
;RW:Trigger on a read or write bus cycle.
;D:Disable trigger (set trigger value, but disable trigger).
LIR:Trigger on a specific value for LIR signal.
LIR=H triggers when LIR is high.
LIR=L triggers when LIR is low.
LIR=X triggers when LIR is high or low.
If either the address or the data value of this command is a range, the analyzer
interprets both values as ranges. For example, the analyzer interprets the command
STC 8 20..40 as STC 8.. 8 20..40; it interprets the command STC 8..9
20 as STC 8..9 20..20.
If the command lacks any R, W, or RW value, the trigger defaults to read/write.
You can set the LIR signal with the clips (bit 6) or the LIR option.
