DCK0[7:0]
LCD clock select
0x000: LCD clock = OSCCLK
Others: LCD clock/DISPCLK
Note:
Only when OP_OSC[2:0] is 0000, 1110, DISPCLK register is available.
When [DISPCLK 1, DISPCLK 0] = 0X000, LCD clock = OSCCLK
LCD frame = LCD clock/512.
For example:
When LCD is COM4, OP_OSC[3:0] = 1110, oscillator is 12MHz to get 64HZ LCD frame, DISPCLK = 12M/512/64 = 0x16E, LCD
frame = 12M/366/512 = 64.04Hz in fact.
