13.3.4
The LCD controller/driver can be operated in the low-power modes, as shown in table 13.4.
In the subactive, watch, and subsleep modes, the system clock pulse generator stops running, so no
clock signal will be supplied and the display will be stopped, unless
setting bits CKS3 to CKS0 in LCR. Since this may result in a direct current being applied to the
LCD panel, be sure to select
speed) mode the system clock is changed, making it necessary to adjust the frame frequency
setting (in bits CKS3 to CKS0) to avoid a change in frame frequency.

Notes: 1. The subclock pulse generator does not stop, but clock supply is stopped.
2. The LCD driver power supply resistive voltage divider is off regardless of bit PSW.
3. The display will not function unless
