Vertical synchronous, horizontal synchronous, and display output control signal input timing
(Ta
= 10 °C to + 70 °C, VDDE = 3.3 V ± 0.3 V, VDDI = 1.8 V ± 0.15 V, VSS = 0 V)
*1 : During the horizontal sync signal pulse period, the device stops its internal OSDC operation, disabling writing
to the internal VRAM. Therefore, set the horizontal sync signal pulse width and VRAM write cycle to ensure
that : horizontal sync signal pulse width < VRAM write cycle.
Precisely, adjust the command issuance interval not to issue command 2 or command 4 (VRAM write command)
more than twice in the horizontal sync signal pulse width period.
If the above condition is not satisfied, the device may fail writing to VRAM.
*2 : 1H is assumed to be one horizontal sync signal period.
