Function
#U, <address > , <step number>
#U,, < step number>
Executes trace and single step actions of programs and indicates final results alone.
(1) The target program is executed from the address specified in <address> for the frequency
specified in <step number> (65535 possible in decimal code), but the results are not
displayed until after the final instruction is completed.
(2) When the <address> is defaulted, execution starts from the current PC for the specified
number of steps.
Examples #U,100,5
*PC=01AA IR=ADI OR A,B A=5 B=0 X=04F T=03F F=ID.C SP=13
#U,,1
*PC=01AB IR=FFF NOP7 A=5 B=0 X=04F Y=03F F=ID.C SP=13
#
(1) The U command does not run in real time, so the target timer is renewed. (For details
refer to Section 2.3.13, "Limitations during emulation".)
(2) When the H command is input after executing this command, the message, *NO HIS-
TORY DATA* , is displayed. Therefore, the G command must be used to analyze history
data.
