MMDS Commands
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:
0Group A- BRN
1RED
2ORG
3YEL
4GRN
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.
