Every time a specified signal changes, the signal status is memorized in
the trace memory. This function is useful for identifying intermittent
troubles.
This screen can not be displayed with the handy operators panel.

a. TRACE MODE: Select the trace mode
0=Records changes of 1byte signals
1=Records changes of independent 2byte signals
2=Records changes of consecutive 2byte signals
b. ADDRESS TYPE:
0=PMC address is used for tracing address.
1=Physical address is used for tracing address.
c. ADDRESS:Set a tracing address.
d. MASK DATA: The bits to be traced are specified by a hexadecimal
number (2 digits).
For example, to trace the signals at bit 7,6,5 and 0, set E1
(hexadecimal) to MASK DATA.
#7 #6 #5 #4 #3 #2 #1 #0
E1% 1 1 1 0 0 0 0 1
However, even if bit 4,3,2 and 1 changes, tracing (memory
registration) cannot be done but signal status is memorized when a
tracing is executed.
