7. LGOE0 to 2: Programmable waveform
LGOE0 is output on the rising edge of the first LCP1 and repeats every 3 pulses of
LCP1. LGOE1 is the 2nd LCP1 and LGOE2 the 3rd, and they also repeat every 3
pulses of LCP1.
LGOE0 to LGOE2 can be generated by 1/16 clocks of LCP1 cycle set in control
registers (48bits × 3) respectively.
These signals can finely adjust the gate output signal and this will enables fine
adjustment of gate bias (the setting of blanking) or zoom function without
modification of data etc.

Various waveforms can be made ; minimum resolution is 1/16 of LCP1 clock (total 1/48)

LGOEn
(example)
LSB←
Various waveforms can be generated by writing LCDOEn5 to LCDOEn0 registers (48bits for each
*
signal). (When "1" is written, output is High level. When "0" is written, output is Low level. The
direction of data is from LSB to MSB. )
Figure 3.14.20 Details of waveform of LGOEn for gate driver
Note1) The above explanation and figures are given for the setting below.
Condition: <LCDCTL2>CPHP = 1, CPVP = 0
For CPHP = 0, CPVP = 1 setting, LCP0 and LCP1 phases are inverted.
Note2) The minimum resolution of LGOEn is 1/16 of LCP1 cycle.
LCP1= (LCDSCC+1 ) × f
Thus, the minimum resolution of LGOEn is (LCDSCC +1) × f
