BCLK High-speed Operation with External Bus Access

Last Updated:06/08/2017

Question:

When operating BCLK in high speed via an external bus access, sometimes the read-out values do not match the written values. Why is this and where should I check to fix it?

Answer:

You need to check the terminal settings used for external buses. Check the setting of the “DSCR” drive capacity control register and select “High-drive output” for all the terminals which can be set to high speed, and try again.
