33.4.5 LCD Interface Current Buffer Address Register
This register indicates the address of the current frame that is being transmitted by LCDIF.
When the LCDIF is behaving as a master, this address points to the address of the current
frame of data being sent out through the LCDIF. When the current frame is done, the LCDIF
block will assert the cur_frame_done interrupt for software to take action. The block will
also copy the HW_LCDIF_NEXT_BUF_ADDR into this bitfield so that the software can
program the next frame address into the HW_LCDIF_NEXT_BUF_ADDR bitfield. This
address must always be double-word aligned.

HW_LCDIF_TRANSFER_COUNT field descriptions (continued)
Total valid data (pixels) in each horizontal line. The data size is given by the WORD_LENGTH. When input
data is is in YCbCr 4:2:2 format (YCBCR422_INPUT is 1), H_COUNT should be the number of 32-bit words
that should be fetched by the block and the BYTE_PACKING_FORMAT should be 0xF. In 24-bit packed
format (WORD_LENGTH=0x3, BYTE_PACKING_FORMAT=0xF), the H_COUNT must be a multiple of 4
pixels. In 16-bit packed format (WORD_LENGTH=0x0, BYTE_PACKING_FORMAT=0xF), the H_COUNT
must be a multiple of 2 pixels.
