S5PC110_UM 1 0BDISPLAY CONTROLLER
1-100
VIDINTCON0 Bit Description Initial State
11 = FRONT Porch
FRAMESEL1 [14:13] Specifies the Video Frame Interrupt 1 at start of:
00 = None
01 = BACK Porch
10 = VSYNC
11 = FRONT Porch 0
INTFRMEN [12] Specifies the Video Frame Interrupt Enable Control Bit.
0 = Disables Video Frame Interrupt
1 = Enables Video Frame Interrupt
Note: This bit is meaningful when INTEN is high. 0
FIFOSEL [11:5] Specifies the FIFO Interrupt control bit. Each bit has a special
significance:
[11] Window 4 control (0 = disables, 1 = enables)
[10] Window 3 control (0 = disables, 1 = enables)
[ 9] Window 2 control (0 = disables, 1 = enables)
[ 8] Reserved
[ 7] Reserved
[ 6] Window 1 control (0 = disables, 1 = enables)
[ 5] Window 0 control (0 = disables, 1 = enables)
Note: This bit is meaningful if both INTEN and INTFIFOEN are
high 0
FIFOLEVEL [4:2] Selects the Video FIFO Interrupt Level.
000 = 0 ~ 25%
001 = 0 ~ 50%
010 = 0 ~ 75%
011 = 0% (empty)
100 = 100% (full) 0
INTFIFOEN [1] Specifies the Video FIFO Interrupt Enable Control Bit.
0 = Disables Video FIFO Level Interrupt
1 = Enables Video FIFO Level Interrupt
Note: This bit is meaningful if INTEN is high. 0
INTEN [0] Specifies the Video Interrupt Enable Control Bit.
0 = Disables Video Interrupt
1 = Enables Video Interrupt 0
NOTE:
1. If video frame interrupt occurs, you can select maximum two points by setting FRAMESEL0 and FRAMESEL1. For
example, in case of FRAMESEL0=00 and FRAMESEL1=11, video frame interrupt is triggered both at the start of
back porch and front porch.
2. S5PC110 interrupt controller has three interrupt sources related to display controller, namely, LCD[0], LCD[1] and
LCD[2]. (For more information, refer to Chapter 4.1, “Vectored Interrupt Controller”). LCD[0] specifies FIFO Level
interrupt, LCD[1] specifies video frame sync interrupt and LCD[2] specifies i80 done interface interrupt.
