● Stand−by function
When STB = L, the T6K04 is in stand−by state. The internal oscillation is stopped, power consumption is
reduced, and power supply for LCD (V
● Busy flag
When the T6K04 is executing an internal operation (except command STRD), the busy flag is set at logical
"H". The state of busy flag is output on data in response to the command STRD. During the busy flag is "H",
no instruction will be accepted (except command STRD). The busy state period (T) is shown as follows.
2 / f ≤ T ≤ 4 / f

● Oscillation frequency
By using the frequency select pins (FS1, FS2), the T6K04 set the relation between oscillation frequency
(f ) and frame frequency (f
OSC
Next table shows the choice of the frequency select pins (FS1, FS2) and oscillation frequency to set f
35 (Hz). The resistance values are typical values. The oscillation frequency depends on the mounting
condition. So it is necessary to adjust the oscillation frequency to a target value.
