Synopsis

Port Number: 26h

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.
