{f, . ..}
<upper mem addr>
{b . .
J
<format index>
[kj
~tep
region>]
[{b.J
<vI>
[{b.J
<v2>
[kJ
<v3>]]]]
The command is terminated by a carriage return.
Parameters:
region index
lower mem addr
upper mem addr
format index
step region
vl,v2,v3
Trace region index number; a number from
o
to 3.
First memory address in the trace region;
a hexadecimal number in the range 0 to
FFFE.
Last memory address in the trace region;
