WebJul 22, 2024 · This is correct. [...] in the table above the value 00 (or ISC00) is used for INT1. This is your misunderstanding. The value "00" in the table does not mean ISC00. The "Value" column of the table is the value you get by concatenating the bits ISC11 and ISC10. Thus: "Value = 00" means ISC11 = 0 and ISC10 = 0.
