Note to display operation synchronous data transfer using FMARK signal

The above example of calculation gives a theoretical value. Possible causes of variances of internal oscillator should be taken into consideration. Make enough margin in setting RAM write speed for this operation.

FMP bit setting

The microcomputer detects FMARK signal outputted at the position defined by FMP bit. The R61509V outputs an FMARK pulse when the R61509V is driving the line specified by FMP bits. The FMARK signal can be used as a trigger signal to write display data in synchronization with display operation by detecting the address where data is read out for display operation.

The FMARK output interval is set by FMI bits. Set FMI bits in accordance with display data rewrite cycle and data transfer rate.
