Bit Field Type Reset Description
31-16 Reserved R 0h
15-0 data R/W 0h The LCD Controller supports a shared Address/Data output bus
A write to this register would initiate a bus write transaction
A read from this register would initiate a bus read transaction
CPU reads and writes to this register are not permitted if the LIDD
module is in DMA mode (cfg_lidd_dma_en = 1)
If the LIDD is being used as a generic bus interface, writing to this
register can store adr_indx to an external transparent latch holding a
16-bit address
If the LIDD is being used to interface with a character based LCD
panel in configuration mode, reading and writing to this register can
be used to access the command instruction area of the panel
