Ordering Information
24.6
The device provides the user with power-on configuration options that can be set through the use of
external pull-up or pull-down resistors of 4.7 kΩ on certain output pins (see customer visible configuration
pins). These pins are generally used as output only pins in normal operation.
While HRESET is asserted however, these pins are treated as inputs. The value presented on these pins
while HRESET is asserted, is latched when HRESET deasserts, at which time the input receiver is disabled
and the I/O circuit takes on its normal function. Careful board layout with stubless connections to these
pull-up/pull-down resistors coupled with the large value of the pull-up/pull-down resistor should minimize
the disruption of signal quality or speed for output pins thus configured.
24.7
The device requires high resistance pull-up resistors (10 kΩ is recommended) on open drain type pins
including I
