Restrictions:
READ_PACK_DIR should only be used if it is required to swizzle the subwords before
doing RGB to RGB CSC, otherwise the DATA_SWIZZLE field should be used to swizzle
across bytes.
READ_PACK_DIR must be 0 if LCD_DATABUS_WIDTH is 8 bits and
READ_MODE_NUM_PACKED_SUBWORDS =1
If READ_MODE_OUTPUT_IN_RGB_FORMAT bit is set, the following restrictions
should be followed:
Freescale Semiconductor, Inc.
• If LCD_DATABUS_WIDTH = 8 bits, then
• If LCD_DATABUS_WIDTH = 16/18/24 bits, then
READ_MODE_NUM_PACKED_SUBWORDS <= 3.
READ_MODE_NUM_PACKED_SUBWORDS = 1.
