Hello everyone
In the IMX7DRM manual, there is a description of the LCDIFx_AS_CTRL register on page 4286. In the description of bits 19-16 of the LCDIFx_AS_CTRL register, there is some understanding of the description.
MASKAS = 0x0 AS AND PS
MASKNOTAS = 0x1 nAS AND PS
MASKASNOT = 0x2 AS AND nPS
MERGEAS = 0x3 AS OR PS
MERGENOTAS = 0x4 nAS OR PS
MERGEASNOT = 0x5 AS OR nPS
NOTCOPYAS = 0x6 nAS
NOT = 0x7 nPS
NOTMASKAS = 0x8 AS NAND PS
NOTMERGEAS = 0x9 AS NOR PS
XORAS = 0xA AS XOR PS
NOTXORAS = 0xB AS XNOR PS
In the above description: What is AS? What is PS? What is nAS? What is nPS?
What will be the effect of AS, PS, AND, nAS, OR, XNOR?
