This command changes the CPU clock speed on hardware that supports it.
- The TI-83+ CPU will run at 6MHz only.
- The TI-83+SE, TI-84+ and TI-84+SE CPU will run at either 6MHz or 15MHz.
Numerical argument
If you pass a numerical argument to *SPEED the CPU speed will be set accordingly. For example,
*SPEED 15
sets the CPU speed to 15MHz on a TI-83+SE, TI-84+ or TI-84+SE. If you try and set the speed to a rate that the hardware does not support, such as running the above example on a regular TI-83+, a Bad command error is triggered.
SLOW or FAST
SLOW or FAST may be passed to *OSCLI to set the CPU to its slowest or fastest available speed.
*SPEED SLOW
On the regular TI-83+ both SLOW and FAST set the rate to 6MHz. On the TI-83+SE, TI-84+ and TI-84+SE the rates are 6MHz and 15MHz respectively.
