KL82 Passive Pin Filter

[rtoma]

Hi there,

I have a question relating to Passive Pin Filter functionality for input GPIOs for a KL82 part. 

In the KL82 reference manual (attached), page 1598 there is table 53-1. For the Passive Filter Enable Enable Control line is says No for all ports except PTA4.

However in the KL82P121M72SF0 Datasheet  (attached) on page 40, for example the Passive pin Filter after POR comes up as N (Disabled). 

Does this mean that the Passive Pin Filter can be enabled for PTC6 for example? Which is the correct interpretation?

Hi Radu Toma 

According to Reference manual:

Individual input passive filter field supporting enable and disable of the individual input passive filter on selected pins

In both documents it is mentioned there is not passive filter control for all ports except PTA4. N in datasheet is not for disable, it is for no available in the pin.

Best regards
