PORSTb

I/O,P.U.

Power-On-Reset. This line is connected to open drain output of
voltage detector device. When power-up is executed this line
asserted low during apr. 800 ms. Off-board power-on-reset may
be provided when this pin is driven by external O.D. (without pull-
up resistor) logic. Failure to do so might result in permanent
damage to the MSC8101 and / or to ADS logic.
