Programmable Registers
Address:
Re-
33.4.27 CRC Status Register (HW_LCDIF_CRC_STAT)
This register reflects the CRC value of each frame sent out by LCDIF. The CRC is done
on the final output bus, so the value will be dependent on the LCD_DATABUS_WIDTH
bitfield even if the input data is the same.
This register will be updated when the CUR_FRAME_DONE_IRQ is asserted. In the case
of DVI mode, the CRC is calculated for the entire frame, not separately for each field in
the frame.
The CRC equation is as follows:
x
Address:
Re-
33.4.28 LCD Interface Status Register (HW_LCDIF_STAT)
The LCD interface status register can be used to check the current status of the LCDIF
block.
