This halting procedure is required before selecting self-refreshing for the display data storage
VRAM (synchronous DRAM in area 3) or making a transition to standby mode or module standby
mode.
1. Confirm that the LPS1 and LPS0 bits in LDPMMR are currently set to 1.
2. Clear the DON bit in LDCNTR to 0 (display-off mode).
3. Confirm that the LPS1 and LPS0 bits in LDPMMR have changed to 0.
4. Wait for the display time for a single frame to elapse.
