Table 16-6. LCD Waveform Base Clock Selection
DUTY[1:0] — Duty Cycle Select
LCLK[2:0] — LCD Waveform Base Clock Select
These read/write bits select the duty cycle of the LCD driver output
waveforms. The multiplexed FP0/BP3 pin is controlled by the duty
cycle selected. Reset clears these bits.
These read/write bits selects the LCD waveform base clock. Reset
clears these bits.
