14.10.88 MIPIA_CMD_LEN—Offset B114h
mipi A clm length
Access Method
Default: 00000000h
14.10.89 MIPIA_RD_DATA_RETURN0—Offset B118h
In addition to the command and data registers, adapter provides 8 read only registers
for S/W to read the return data from the panel. At this time the usage case for the read
path from the panel is for configuration reads only. Hence, more than 4 bytes of read
are not allowed. Maximum read return size in the MIPI IP should be no greater than 32
bytes.
