TIMING FOR CONTINUOUS COMMAND INPUT
When inputting commands continuously, the following timing requirements must be observed:
(T
A
= –20 to +75C, V
DD
= 2.7 to 5.5 V)
f
OSC
: Frequency of LC oscillation or external input clock (MHz), S: Character size (single (minimum) or double), t
HWL
: Hsync width.
Commands other than VRAM write commands may not comply with T2 provided the control clock cycle satisfies the specifications.
