13.2.2
LCR is an 8-bit read/write register which performs LCD drive power supply on/off control and
display data control, and selects the frame frequency.
LCR is initialized to H'80 upon reset.
Bit 7—Reserved
Bit 7 is reserved; it is always read as 1 and cannot be modified.
Bit 6—LCD Drive Power Supply On/Off Control (PSW)
Bit 6 can be used to turn the LCD drive power supply off when LCD display is not required in a
power-down mode, or when an external power supply is used. When the ACT bit is cleared to 0,
or in standby mode, the LCD drive power supply is turned off regardless of the setting of this bit.

Bit 5—Display Function Activate (ACT)
Bit 5 specifies whether or not the LCD controller/driver is used. Clearing this bit to 0 halts
operation of the LCD controller/driver. The LCD drive power supply is also turned off, regardless
of the setting of the PSW bit. However, register contents are retained.
