11.10 Free programmable multiplex rate
The free programmable multiplex rate concept allows the
usertolimitthenumberofrowsselectedtogroupsofeight.
Any, or all of these groups of rows can be enabled or
disabled. The mask register command (M[7:0]) allows the
user to turn-on or turn-off blocks of eight rows.
Each mask value controls a block of eight rows, thus in
partial mode the maximum number of rows available is
64 plus the icon row. A logic 1 in the mask register enables
the rows available within that block of rows, and a logic 0
disables them.
The mask register causes the row counter to count eight
bits and then jump to the next enabled 8-bit group. For
example, if the mask register value is 00001101, then the
rows available will be 0 to 7, 16 to 23, 24 to 31 and 67.
Rows 8 to 15 and 32 to 63 have been skipped. This
information is also mapped to the RAM so that only the
contents of active rows are displayed.
