21.7.2 Idle Mode

The SENT module provides two options of operation when the device enters Idle mode. If SIDL (SENTxCON1[13]) = 1, module operation stops when the device enters Idle mode. The same system considerations described in Sleep mode apply.

If SIDL = 0, the module will continue the transmission or reception process after the device enters Idle mode. When operating in Transmitter mode, the module will continue to send messages with the data contained in SENTxDAT unless the device wakes from Idle to write new data. If the module is operating in Receive mode, any old data in the SENTxDAT register will be lost unless the device wakes from Idle to read the data.
