The order in which the rows are activated is a function of
bits MY, TRS, BRS and the selected multiplex rate.
Tables 9 to 12 give the order in which the rows are
activated. In all cases, the RAM is accessed in a linear
Table 9 Row order for BRS = 0 and TRS = 0
Table 10 Row order for BRS = 1 and TRS = 0
Table 11 Row order for BRS = 0 and TRS = 1
Table 12 Row order for BRS = 1 and TRS = 1

jumping to the end for the icon data. When MY = 1, the
RAM is still accessed in a linear fashion but starting from
the last row, counting down to zero and then jumping to the
icon data.
