[TI-H] TI-83P SE hardware, looking for thoughts




Hello,

The interrupt freq varies with the voltage supplied by the batteries.
When they use an RC oscillator
A real test must be don with a constant voltage power supply (something
like +-0.1% to see anything).
Besides that a 32768Hz crystal normally are used in RTC and PLLs.
I'll check your graphs to try to discover something (I'm working with
some z8s180 but they use a normal oscillator with a XMHz crystal).

Ale
