Registers
LCDC/DMA registers are shown below. LCDC
register is initialized at the system initialization. After
setting each parameter, set the DMA start bit to ‘1’
and execute HALT instruction, then DMA transfer
starts.

LCH (Display horizontal timing register)
Bit 7

Bits 7 to 6 : Set ‘0’.
Bit 5 : H-dot size bit
BIT
0
160
1
200
Bits 4 to 0 : H-timing bits
NOTE :
V-blank width bit must not be filled with 0000B. Otherwise,
LCDC interrupt can not be effective.
Horizontal display cycle = (shift clock x LCDC/DMA
clock ) x (H-timing + 1)
Shift clock = 40 (at H-dot size = 160),
50 (at H-dot size = 200)
Frame cycle = Horizontal display cycle x (V-line
size + V-blank width)
