;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.

SP 8 20

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
