Synopsis

Port Number: 22h

Function: Flash Execution Lower Limit

This port controls the first of two flash page execution limits.

Read Values

  • [00h - FFh]: Flash Pages at or below this value have execution permission. This is always set to 08 in TIOS.

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 code from a page above this port's value and below the value in Port 23 will cause the calculator to reset.
