“The number of bytes is equal to 2**[Length Width]. So a Length Width of 26 gives a byte count of 67,108,863 bytes.”

So, obviously, my understanding was wrong. Maybe each combination is responsible for 1 byte of data (i am just assuming). Might be the software driver for maximum btt is 8MB for contiguous memory, but don’t explain about 2KB at 14bit buffer length register.
