26.3.20 LCDC User Specified Interrupt Control Register (LDUINTR)
LDUINTR sets whether the user specified interrupt is generated, and indicates its processing state.
This interrupt is generated at the time when image data which is set by the line number register
(LDUINTLNR) in LCDC is read from VRAM.
This LCDC issues the interrupts (LCDCI): user specified interrupt by this register, memory access
interrupt by the LCDC interrupt control register (LDINTR), and OR of Vsync interrupt output.
This register and LCDC interrupt control register (LDINTR) settings affect the interrupt operation
independently.

Specifies the start and stop of the LCDC display
operation.
The control sequence state can be checked by
referencing the LPS[1:0] of LDPMMR.
0: Display-off mode: LCDC is stopped
1: Display-on mode: LCDC operates
Description
