Care should be exercised when using the block read or block
write modes. For most cases, block reading or writing to a
register automatically increments the register address to point
to the next register. The exceptions to this case are the indirect
memory address registers, transmitter user bit and receiver user
bit data buffers. Using a block read or write to access these
registers does not update the absolute register address, but
instead updates the buffer address to provide the next value in
the buffer.
