STEPTIL
Single Step to Address
STEPTIL
The STEPTIL command continuously executes instructions from the
current program counter (PC) address value until the PC reaches the
specified address.
Syntax:
STEPTIL < address>
Where:
< address> The address at which instruction execution
stops; this location must be an instruction
address.
NOTE:
Do not use any step command (ST, STEP, STEPFOR, STEPTIL, or T)
if the PC points to internal 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.
Example:
>STEPTIL 0400 Execute instructions continuously until
the PC value is 0400 during an opcode
fetch cycle.
