MMDS Commands

A–73MMDS0508 Target Interface

;R: Search for a read bus cycle only.

;W :Search for a write bus cycle only.

;RW: Search for either a read or write bus cycle.

LIR: Search for a specific LIR-signal value:

LIR=H searches for LIR high.

LIR=L searches for LIR low.

LIR=X searches for LIR either high or low.

A bit set in both the clips and masks detects the pattern if the bit is high (-H). A bit is

clear in clips but set in masks detects the pattern if the bit is low (-L). A bit clear in a

mask means that pattern detection does not depend on the state of the clip.

Examples:

SP 0x1000

Sets accesses at address $1000 to be part of the analyzer search pattern.

SP,4

Sets accesses with the data value 4, at any address, to be part of the analyzer search

pattern.

SP820

Sets accesses with the data value 20, at address 8, to be part of the analyzer search

pattern.

NOTE Mask bits that have the value 0 are “Don’t Care” bits: for those

positions of an address, data, or clips value, either a 0 or a 1 trips the

trigger. Mask bits set to 1 identify positions whose values must match

those of the specified address, data, or clip value. For Address

0xC000, Mask 0xFFFC, loading any of four values in the address bus
