Description
Parallel Interface Data Input Pins
For 8–bit RED Display: DI7 = R7 – MSB, DI0 = R0 – LSB.
Parallel Interface Data Input Pins
For 8–bit GREEN Display: DI15 = G7 – MSB, DI8 = G0 – LSB.
Parallel Interface Data Input Pins
For 8–bit BLUE Display: DI23 = B7 – MSB, DI16 = B0 – LSB.
Control Signal Input
For Display/Video Application: CI1 = Data Enable Input
Control signal pulse width must be 3 clocks or longer to be transmitted when the Control
Signal Filter is enabled (CONFIG[1:0] = 01). There is no restriction on the minimum
transition pulse when the Control Signal Filter is disabled (CONFIG[1:0] = 00). The signal
is limited to 2 transitions per 130 clocks regardless of the Control Signal Filter setting.
Control Signal Input
For Display/Video Application: CI2 = Horizontal Sync Input
Control signal pulse width must be 3 clocks or longer to be transmitted when the Control
Signal Filter is enabled (CONFIG[1:0] = 01). There is no restriction on the minimum
transition pulse when the Control Signal Filter is disabled (CONFIG[1:0] = 00). The signal
is limited to 2 transitions per 130 clocks regardless of the Control Signal Filter setting.
Control Signal Input
For Display/Video Application: CI3 = Vertical Sync Input
CI3 is limited to 1 transition per 130 clock cycles. Thus, the minimum pulse width allowed
is 130 clock cycle wide.
