Question:

I'm having trouble performing initial settings using the MD pin. What are the possible causes?

Answer:

The MD pin is taken in at the rising edge of the reset pin (PRESET#). After it is taken in, it automatically switches to default function. If you are connecting the MD pin to an external chip, please check that a signal is not being output from the external chip while the reset pin level (PRESET#) is rising.

The setup/hold time of PRESET# and the MD pin are stipulated by AC, so please check whether these are being adhered to.
