42.6.6 Sleep Mode Operation
The SLCD can be configured to operate in any sleep mode. To be able to run in standby mode, the RUNSTDBY bit in the Control A register (CTRLA.RUNSTDBY) must be written to '1'. The SLCD will continue to refresh the LCD panel from the content of the memory display. If the RUNSTDBY bit is written to '0' when device enters into standby mode, the SLCD will stop driving the LCD panel at the end of the current frame, and the VLCD and bias generators will be stopped.
The SLCD can wake up the device from any sleep mode using interrupts.
