Calculator's Interrupt Routine
« on: December 29, 2010, 06:15:56 pm »
Does anyone know EVERYTHING that the TI-83+ does during im 1?  I know it checks the link port, decrements APD, checks the keypad and blinks the cursor, but I'm wondering if there's anything else.  I'm trying to decide if it's worth disabling from time to time.

It uses around (at least) 1100 clock cycles every time its called and theres no downside to disabling it if you dont need to update/check any of that stuff. If you want the speed, disable it.

*The timing is based off of a ti84+ interrupt.
