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:

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.
