Function

BSTR

Sets the write mode for writing data to the display RAM.

If the high-speed RAM write mode is selected, data is written to the display RAM in 2-pixel

units inside the

µ PD161623. When selecting the high-speed RAM write mode, be sure to write

data to the display RAM in 2-pixel units.

0: Normal write mode (18-bit access: 4 MHz MAX.)

1: High-speed RAM write mode (36-bit access: 8 MHz MAX.)
