Within the table, the ‘Minimum MCLK’ column gives the recommended memory clock
frequency at which the 69000 can run without adverse effects to functionality. Better
benchmarks can be achieved with an MCLK frequency higher than the frequency specified.
DSTN flat panels require display memory for frame accelerator functionality.
For simultaneous operation, both the flat panel and the CRT monitor must be configured at
a minimum to support the resolution of a given display mode.
