Executes trace, and single step actions of programs.

(1) The specified portion of the target program executes with a frequency indicated by the

<step number> from the specified <address> (65535 possible in decimal code). The PC,

instruction word and register contents are displayed with each execution.

(2) When the <step number> is defaulted, only one step is executed.

current PC (PC at which the previous T command completed).

current PC. When this setting occurs after power on, one step is executed from PC=0100.

(5) When the <step number> is one (#T, <address> or #T), the instruction does not terminate

after one step, but a further step is executed by the "SP" key input, at which time the

instruction can be terminated by the "ESC" key input.
