| This port only exists as a distinct port on the TI-83 Plus Silver Edition, the TI-84 Plus, and the TI-84 Plus Silver Edition. On the standard TI-83 Plus, it acts as a shadow of port 03. |
Synopsis
Port Number: 23h
Function: Flash Execution Upper Limit
This port controls the upper of two flash execution limits.
Read Values
- [00h - FFh]: Flash pages above this value have execution permission. In TIOS this will be set to the last app page minus one.
Write Values
- [00h - FFh]: The new execution limit. You must enable flash access through port 14 first.
Comments
This port does not exist on the standard 83 Plus. See ports 5 and 16 instead. Execution of code from a page at or below this port's value and above the value in port 22 will cause the calculator to reset.
