46.5.2 Idle Mode
When the device enters Idle mode, the QEISIDL bit (QEIxCON<13>) determines whether the QEI module stops in Idle mode or continues to operate in Idle mode.
If QEISIDL = 1
, the QEI module enters into a power-saving mode and performs
the same functions as in Sleep mode. If QEISIDL = 0
, the module does not
enter into a power-saving mode and continues operation in Idle mode.
