MSP430G2312とMSP430Gシリーズに関する質問があります。
ポートがI / O入力に設定され、内部プルアップおよびプルダウン抵抗が有効になっている場合

機械的接触スイッチが外部から直接接続されている場合、オン/オフの接触によるポートのシンクとソースの電流はいくつありますか?

また、同じ仕様で、チャタリング対策のためのフィルタコンデンサの適切な値は
いくつですか?

ご不便をおかけして申し訳ございませんが、ご回答いただき、ありがとうございます。

Hi guy,

Sorry I can't understand Japanese. Could you descript your question in English.

Google translate:

I have a question about the series.
When the port is set to I / O input and internal pull-up and pull-down resistors are enabled

If the mechanical contact switch is connected directly from the outside, what is the current of the port sink and source due to the on / off contact?

Also, with the same specifications, the appropriate value of the filter capacitor for chattering countermeasures is
How old are you?

We apologize for any inconvenience, and thank you for your response.
