Row
The OSD module has 4 row buffers for displaying on-screen characters; row 0, 1, 2 and 3. Each
row buffer consists of 32 pairs of Character register pairs (See Section 9.3). There are 5 registers
which affects the position and attributes of the display rows.
9.4.1
Row Attribute Register
MTRXi - Character dot matrix select for row i
1 (set)
12x16 character dot matrix selected for row i.
0 (clear) –
16x16 character dot matrix selected for row i.
If 12x16 matrix is selected, a maximum of 32 characters may be displayed for that row. Rows
selected for 16x16 matrix characters, the maximum is 24 characters per row; the remaining 8
