6.6.2 Buffer memory comparisons
(1) A/AnS series
Buffer memory is divided into bank0 to bank2 on the A/AnS series, but it is one area on the Q series.
Bank is switched with ON/OFF of Y (n+1)C, Y(n+1)D.
Buffer memory address of the Q series is shown in parenthesis, as buffer memory addresses of
communication buffer and automatic updating buffer are different.
