T
Single Step (Trace)
T
The T command executes a specified
hexadecimal number of
instructions beginning at the current program counter (PC) address
value. If a number is not specified, this command executes one
instruction. The T, ST, and STEP commands are identical.
Syntax:
T [<
count>]
Where:
<
count>
The
hexadecimal number of instructions to be
executed. Hexadecimal $7FF is the maximum
value.
NOTE:
Do not use any step command (ST, STEP, STEPFOR, STEPTIL, or T)
if the PC points to internal RAM (for instance, option RAM) or EEPROM
or if the code branches into internal RAM or EEPROM.
The step commands are not real-time. They execute one instruction at a
time, then return control to the monitor. Do not rely on timer values.
Examples:
>T
Execute the instruction at the current PC address
value.
>T 4
Execute four instructions beginning at the current PC
address value.
