8.8.2 LCD Clock Register (LCDCLK)
The LCD clock register (LCDCLK):
Selects the fast charge duty cycle
Selects LCD driver duty cycle
Selects LCD waveform base clock
FCCTL[1:0] — Fast Charge Duty Cycle Select
These read/write bits select the duty cycle of the fast charge duration. Reset clears these bits.
(See
8.4.4 Fast Charge and Low Current
)
Table 8-4. Fast Charge Duty Cycle Selection
DUTY[1:0] — Duty Cycle 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.
Table 8-5. LCD Duty Cycle Selection
LCLK[2:0] — LCD Waveform Base Clock Select
These read/write bits selects the LCD waveform base clock. Reset clears these bits.
