State Qualifiers
Whenever a state can be specified in the trace command (trigger state,
storage state, prestore state, etc.), you will see the following softkeys that
allow you to qualify the state:
address
The value following this softkey is searched for on the lines that monitor the
emulation processor's address bus.
data
The value following this softkey is searched for on the lines that monitor the
emulation processor's data bus.
status
The value following this softkey is searched for on the lines that monitor
other emulation processor signals.
When a value is specified without one of these softkeys it is assumed to be an
address value.
Predefined Values for Qualifiers When you specify status qualifiers
for analyzer states (by pressing the status softkey), you will be given the
following softkeys which are predefined values for the qualifiers.
Qualifier Status Values
berr
=0xxxxx0xxxxxxxxxx BIN - bus cycle bus error
data
=0xxx1xxxxxxxxxxxx BIN - bus cycle is a data transfer
flush
=0xx0xxxxxxxxxxxxx BIN - instruction pipe flush and program transfer
halt
=0xxxx0xxxxxxxxxxx BIN - processor halt
hibyte
=0xxxxxxxxxxxxxxx
lobyte
=0x0xxxxxxxxxxxxxx BIN - low byte bus transfer
prog
=0xxx0xxxxxxxxxxxx BIN - bus cycle is an instruction fetch
read
=0xxxxxxxxxxx1xxxx BIN - bus cycle is a read
write
=0xxxxxxxxxxx0xxxx BIN - bus cycle is a write
These predefined values may be used as other values would be used.
For example:
trace after status write
is the same as:
trace after status 0xxxxxxxxxxx0xxxxb
208
Description
BIN - high byte bus transfer
