22.3.12 LCDC PWM Contrast Control Register (LCD_PCCR)
The PWM contrast control register is used to control the signal output at the contrast pin, which controls
the contrast of the LCD panel.
22.3.13 LCDC DMA Control Register (LCD_DCR)
There is a 32
×
32 bit line buffer in the LCDC that stores DMA data from system memory. The DMA
control register controls the DMA burst length and when to trigger a DMA burst in terms of the number
of data bytes left in the pixel buffer.
Address: 0xFC0A_C02C (LCD_PCCR)
Access: User read/write

Description
31–25
Reserved, must be cleared.
24–16
CLS_HI_
WIDTH
LCD_CLS high pulse width. Controls the pulse width of LCD_CLS in units of LCD_LSCLK. The actual pulse width
is CLS_HI 1.
15
LDMSK
LD mask. Enables/disables the line data (LCD_D[17:0]) output to zero for the Sharp TFT panel power-off sequence.
0 LCD_D[17:0] is normal.
1 LCD_D[17:0] always equals 0.
14–11
Reserved, must be cleared.
10–9
SCR
Source select. Selects the input clock source for the PWM counter. The PWM output frequency is equal to the
frequency of the input clock divided by 256.
00 Line pulse
01 Pixel clock
10 LCD clock (f

)
11 Reserved
8
CC_EN
Contrast control enable. Enables/disables the contrast control function.
0 Contrast control is off.
1 Contrast control is on.
7–0
PW
Pulse width. Controls the pulse width of the built-in pulse width modulator, which controls the contrast of the LCD
screen.
