The T coomand may be used at any time even if the Target program is being
executed. If the Target program is not executing, the Trace printout will
begin as soon as (CR) is entered for the T command. If the History module
is not sampling (sampling stops if the Trigger word/strobe compares and no
hardware breakpoint is set) the Trace printout will also begin immediately.
If the History module is sampling, then the word "SAMPLING" will be printed.
The user may then enter either (CR) or (.) If (.) is entered the AIM monitor
will be reentered with no changes. If (CR) is entered, the history sampling
will be tenninated and the Trace printout begun.
Fonnat (2) allows the number of lines of history printed to be specified.
The operand "n" is a hexadecimal number between 1 and 0FFH which specifies
the number of lines printed.
Format (3) is used to specify the offset from the breakpoint in the history
RAM to begin display. The second operand "0" is a signed hexadecimal number
between -3FFH and 3FFH which specifies this offset. If an offset is
specified which is before the start of the history, the earliest sample is
the default. If an offset is specified which is after the end of history,
the n~st recent sample is the default.
Fonnat (4) is used to specify the display format "f". The display format is
a hexadecimal digit for which each bit enables a specific field of the
history printout. The field enabled by each bit follows.
Bit 0 = 1
Bit 1 = 1
Bit 2 = 1
Bit 3 = 1
