25.2.19 LCDC Control Register (LDCNTR)
LDCNTR specifies start and stop of display by the LDCD.
Bits 15 to 1—Reserved
Bit 4— Display start auxiliary bit (DON2): Specifies the start of display operation using LCDC.
LCDC operation cannot be guaranteed if 0 is written to this bit at any time other than the start of
display operation. Note that a 1 written to this bit is automatically cleared to 0, so it is not
necessary to write 0 to it in order to clear it.
Bit 0—Display On (DON): Specifies the start and stop of the LCDC display operation.
The control sequence state can be checked by referencing the LPS value in bit 0 of the LCDC
power management mode register (LDPMMR).
