The Generic Read Request with 2 parameters will be used for reading DSIx6 CFR registers. The current address space requirement for the SN65DSI86 is just 256 bytes. This means the MS Byte of ADDR (bits 15 to 8) will always be zero. The MS Byte of the ADDR is intended for future expansion. The SN65DSI86 response size defaults to one byte as defined by [DSI]. Software can use the Set Maximum Return Packet Size to inform the DSI86 that the GPU can support more than one byte, but the DSIx6 will always provide a response of one byte. If a single-bit ECC error was detected and corrected in the request, the DSIx6 will provide the requested data along with an Acknowledge and Error Report packet. If multi-bit ECC errors are detected and not corrected, the DSIx6 will only respond with an Acknowledge and Error Report packet.
