Initial
Bit
Bit Name Value R/W Description
8
UINTEN 0
R/W User Specified Interrupt Enable
Sets whether generate an LCDC user specified
interrupt.
0: LCDC user specified interrupt is not generated
1: LCDC user specified interrupt is generated
7 to 1 ⎯
All 0 R
Reserved.
These bits are always read as 0. The write value should
always be 0.
0
UINTS
0
R/W User Specified Interrupt State
This bit is set to 1 at the time an LCDC user specified
interrupt is generated (set state). During the user
specified interrupt handling routine, this bit should be
cleared by writing 0 to it.
0: LCDC did not generate a user specified interrupt or
has been informed that the generated user specified
interrupt has completed
1: LCDC has generated a user specified interrupt and
has not yet been notified that the generated user
specified interrupt has completed
Notes: Interrupt processing flow:
1. Interrupt signal is input
2. LDINTR is read
3. If MINTS, FINTS, VSINTS, or VEINTS is 1, a generated interrupt is memory access
interrupt, flame end interrupt, Vsync rising edge interrupt, or Vsync falling edge
interrupt. Processing for each interrupt is performed.
4. If MINTS, FINTS, VSINTS, or VEINTS is 0, a generated interrupt is not memory access
interrupt, flame end interrupt, Vsync rising edge interrupt, or Vsync falling edge
interrupt.
5. UINTS is read.
6. If UINTS is 1, a generated interrupt is a user specified interrupt. Process for user
specified interrupt is carried out.
7. If UINTS is 0, a generated interrupt is not a user specified interrupt. Other processing is
performed.
