I want use the EMIOS's QDEC mode,if I configure UC(n)'s mode=0b0001101, then UC(n-1)'s mode should also be configured mode=0b0001101? or I don't need do anything about UC(n-1)'s mode?

I want use the EMIOS's QDEC mode,if I configure UC(n)'s mode bit=0b0001101, then UC(n-1)'s mode bit should also be configured to mode=0b0001101? or I don't need do anything about UC(n-1)'s mode configuration, it will automatically choose this mode?

Hi, you cannot configure QDEC for UC(n-1) channel, it would be conflicting configuration.

Either don't configure anything for UC(n-1) channel or it can be used for an operation mode that does not use I/O pins, such as MC mode (modulus counter).
