Invert Pixel Clock
DescriptionValue
Data is driven on the LCD's data lines on the rising edge of
LCDCP.
0
Data is driven on the LCD's data lines in the falling edge of
LCDCP.

For Active Matrix output (LCDTFT=1), the Output Pixel Clock is a free
running clock in that it transitions in horizontal blanking (including
horizontal front porch, horizontal back porch) areas and all vertical
blanking times.
For Passive Matrix output (LCDTFT=0), the Output Pixel Clock on occurs
when an output data value is written. It is in a return-to-zero state when
INVPXLCLK=0 and a return-to-one state when INVPXLCLK=1.

DescriptionValue
LCDLP pin is active high and inactive low0
LCDLP pin is active low and inactive high1
Active and passive mode: horizontal sync pulse/line clock active between
lines, after the end of line wait period

Invert Vsync
DescriptionValue
LCDFP pin is active high and inactive low0
LCDFP pin is active low and inactive high1
Active mode: vertical sync pulse active between frames, after end of
frame wait period
Passive mode: frame clock active during first line of each frame

AC Bias Pins Transitions per Interrupt
Value (from 0x0 to 0xF) used to specify the number of AC Bias pin
transitions to count before setting the line count status (ACBS) bit,
signaling an interrupt request. Counter frozen when ACBS is set, and is
restarted when ACBS is cleared by software. This function is disabled
when ACBI = 0x0000.
0x0RWACBI19:16
AC Bias Pin Frequency
Value (from 0x0 to 0xFF) used to specify the number of line clocks to
count before transitioning the AC Bias pin.
This pin is used to periodically invert the polarity of the power supply to
prevent DC charge build-up within the display. ACBF = Number of line
clocks/toggle of the LCDAC pin.
0x00RWACBF15:8
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
