Bit 12—Vsync Interrupt Select (VINTSEL): Sets the starting point of the LCDC’s Vsync
interrupt.

Bit 8—Vsync Interrupt Enable (VINTE): Sets whether or not to enable LCDC’s Vsync
interrupts.

Bit 0—Vsync Interrupt State (VINTS): Indicates the LCDC’s Vsync interrupt handling state.
This bit is set to 1 at the time a Vsync interrupt is generated. During the Vsync interrupt handling
routine, this bit should be cleared by writing 0 to it.

Notes: • Interrupt Handling Flow:
• When Vsync interrupts are enabled, the VINTE bit must be set to 1 before the DON bit
1. An interrupt signal is input to the CPU.
2. The CPU reads from VINTS.
3. If VINTS is set to 1, a Vsync interrupt has occurred, and the Vsync interrupt
4. If VINTS is cleared to 0, no Vsync interrupt has occurred and another processing is
is set to 1, and the VINTE bit must not be cleared to 0.
