24.8.3 When the Device Enters Idle Mode

When the device executes a PWRSAV 1 instruction, the device enters Idle mode. The module enters a Power-Saving state in Idle mode, depending on the I2CSIDL bit (I2CxCON1[13]). If I2CSIDL = 1, the module enters a PowerSaving mode, similar to actions while entering Sleep mode. If I2CSIDL = 0, the module does not enter a Power-Saving mode and continues to operate normally.
