Do SH7286 analog output-dedicated pins do not shift to HiZ in reset?

Latest Updated:09/11/2012

Question:

The SH7286 analog output-dedicated pins (DA0 and DA1) don't change to the HiZ state immediately in the reset state.

Answer:

The SH7286 analog output pins cannot be brought to the HiZ state immediately after entering the reset state (low level input to the RES pin). They enter the HiZ state after keeping the DA output level for a while. However, any value other than D/A data register setting value before low level input to the RES pin cannot be output.
